Surviving the Titanic - Part 1

Algebra Level 1

The Titanic had a total capacity (passengers + crew) of 3353. If she carried the following lifeboats:

  • 14 × \times 65-passenger wooden lifeboats,
  • 4 × \times 47-passenger collapsable canvas lifeboats, and
  • 2 × \times 40-passenger emergency cutters,

how many people would we expect to go down with the ship in a catastrophe?

Total capacity = 3353 =3353 . According to the question, we get the number of people who could accomodate the lifeboats.

No. of people who could accomodate the lifeboats = 14 × 65 + 4 × 47 + 2 × 40 = 910 + 188 + 80 = 1178 =14\times 65 + 4\times 47 + 2\times 40 = 910+188+80 =\boxed{1178}

Now, people who would go down with the ship are the remaining people who couldn't accomodate the lifeboats and the number of those people are = 3353 1178 = 2175 =3353-1178 = \boxed{2175}

easy :) nailed it

total capacity of life boats 1178 less capacity 3353= 2175

where do you get + 188 + 80

@Reginald Pilar If you use the order of operations like BODMAS, then you calculate the multiplication parts first and then add the values. So ---->

( 14 × 65 ) = 910 , 4 × 47 = 188 , ( 2 × 40 ) = 80 (14\times 65)=910,\quad 4\times 47=188,\quad (2\times 40)=80

Adding them all together, we get ( 910 + 188 + 80 ) = 1178 (910+188+80)=\boxed{1178} . These are the people who can accomodate the lifeboats. So, now subtract them from the total 3353 3353 people to get the no. of people who couldn't accomodate the lifeboats.

We dont have that information in the problem!! This is a math problem, not a history or philosophy problem. -_-

Prasun Biswas - 7 years, 2 months ago

answer is not determined because if some of the people on the ship knew swimming then the answer would be less . lol..

Actually not, since the ship hit the iceberg near the arctic circle and that too, at night, so the ocean waters are very very cold at that time. As a result, if someone even knew swimming, he/she would die of hypothermia before he/she could even reach the shore and may I point out that the shore is many many miles away, so he/she would need to swim continuously for 23-24 hours, I think..!!

14 MULTIPLY BY 65 = 910 4 MULTIPLY BY 47 = 188 2 MULTIPLY BY 40 = 80 PLUS THESE ALL RESULTS 910+188+80= 1178 NOW CAPACITYOF TITANIC TO HOLD 3353 PASSENGERS THEREFORE 3353 - 1178 = 2175 SO THERE ARE 2175 PEOPLE WOULD WE EXPECT TO GO DOWN WITH THE SHIP IA CATASTROPHE

Prasun Biswas - 7 years, 2 months ago

I got the correct answer but... WAIIIT!!!! IT SAID PASSENGERS!!! THE TOTAL OF PASSENGERS AND CREWS ARE 3353. It only asked how many people will drown. It is not equal for passengers and crews per lifeboat. If we assume that there are more passengers than crews in every lifeboat then i can say our answer is wrong.

If 14 x 65 - passenger wooden lifeboats - save 910 people plus 4 x 47 - passenger collapsable canvas lifeboats - save 188 people plus 2 x 40 passenger emergency cutters - save 80 people. Total of people saved = 2175. Total of people in ship = 3353. People expect to go down with the ship: 3353 minus 1178 = 2175.

Totaled 14x65,4x47,2x40 that is 1178. from total no of persons on ship 3353,subtracted 1178 yhat is 2175 Answer.

14 * 65 = 910 4 47=188 2 40=80 so, total capacity (a) = 3353, total saved: (b) 910+188+80 = 1178. x=a-b x= 3353-1178 = 2175

14 multiply 65 = 910, 4 multiply 47 = 188, 2 multiply 40 = 80, all is equal of 1178, the passenger on titanic are 3353, 3353 - 1178, 2175 Answer

Simply, people who would go down with the ship are the remaining people who couldn't accomodate the lifeboats and the number of those people are 3353-1178=2175

Waqas Khan

its simple way to solve this first multiply 14X65+4X47+2X40=1178 then total capacity=3353 -1178=2175

Wajid Anwar

Total capacity=3353 . According to the question, we get the number of people who could accomodate the lifeboats.

No. of people who could accomodate the lifeboats =14 65+4 47+2*40+1178 Now, people who would go down with the ship are the remaining people who couldn't accomodate the lifeboats and the number of those people are 3353-2175

14 65= 910 4 47=188 2*40=80

910+188+80= 1178

3353-1178= 2175

the number of passengers that survived by wooden lifeboats = 14 65=910 passenger the number of passengers that survived bycollapsable canvas lifeboats = 4 47=188 pasenger the number of passengers that survived by emergency cutters = 2*40 =80 passenger so the total survived = 910+80+188=1178 passenger and since the total capacity =3353 so the number od non survived people = 3353-1178 =2175 (the answer)

Muhamed Medo
Mar 6, 2014

the number of people that accomodate the wooden lifeboats =14 \times 65 = 910 the number of people that accomodate the collapsable canvas lifeboats = 4 \times 47 =188 the number of people that accomodate the emergency cutters = 2\times 40 = 80 so the total survived passengers = 910+188+80=1178 ,since the total capacity =3353 therefore the number of people that we expect to go down with the ship in a catastrophe =3353-1178 = 2175 persons and this is the answer

Simply multiply each equation then add all the products then subtract it into 3353.

Laxman Selvam

passengers drowned = 3353 - (14 65) - (47 4) - (2*40) = 2175

total no. of people=3353 No. of people accommodate in life boat = 14 65+4 47+2*40=910+188+80 =1178 Now, people who would go down with the ship are the remaining people who couldn't accomodate the lifeboats and the number of those people are 3353-1178=2175

Total capacity=3353 . from the question, we get the number of people who could accomodate the lifeboats.

No. of people who could accomodate the lifeboats =14 x 65 + 4 x 47 + 2 x 40 =1178

Now, people who would go down with the ship are the remaining people who couldn't accomodate the lifeboats and the number of those people are = 3353 - 1178 = 2175

Mohammad Zameer

(14 * 65)+(4*47)+(2 * 40)=1178 who can survive using the lifeboats if we subtract this figure from whole the remaining will go down 3353-1178=2175

Nina Acain

Multiply the number of life boat to its capacity then add to other products of other lifeboats. 3353 minus the total passengers which is 1178 equals to 2175.

Waqaar Baig
Feb 19, 2014

simple : 14 x 65 + 4 x 47 + 2 x 40 = 910 + 188 + 80 + 1178 Those who drowned with the ship are 3353 - 1178 = 2175

Namrata Nayak
Feb 19, 2014

given, total no of people= 3353 total no of people who could use life boat = 14 65 + 4 47 +2*40 = 1178 so, no of people who were expected to go down = 3353 - 1178 = 2175

Libs Ahmed

14 * 65=910 4 *47=188 2 * 40=80

add up 910+188+80=1178 3353-1178=2175

Hasnain Shabbir

Simply,multiply the (14 65),(4 47),(2*40),and then add up all the number of passengers,then finally subtract this amount from total number of passengers,and you get the answer.

Rashmi Agrawal

3353-(14 65+4 47+2*48)=2175

Dhruv Shah
Feb 18, 2014

First, multiply the total number of passengers that can be carried: (14 65) + (4 47) + (2*40) = 1178 Then subtract 1178 by the total number of passenger and crew: 3353 - 1178 = 2175 So 2175 people were expected to go down with the ship.

total capacity in life boats is 1178 and total person in titanic are 3353 so 3353-1178=2175
