Engr. Joanna`s Map
A map is drafted by Engr.Joanna to help the people to familiarize themselves to the city and the scale of the map is 1 inch is to 500 meters. if the distance of the city hall to the park is 0.25 inch. Find how many minutes could a worker run from the park to the city hall at the rate of 25m/s ?
The answer is 5.

error- minute/second
stupid error hahaah i wrote 0.08 minutes XD

you were not the onlyone :D this question has an error
This 2x.
hmmm...the question is wrong
exactly
According to question acceleration is 25m/s^2 because it is written that a worker could run at rate of 25m/s.
lol wrong question XD
wrong question
this is the silliest question ever
The distance from the city hall to the park is 5 0 0 m × 0 . 2 5 = 1 2 5 m. The worker would make it to the city hall from the park in 2 5 1 2 5 = 5 seconds.
Note: This solves for the number of seconds it would take. It would take 1 2 1 minutes to get to city hall. The question needs to be reworded.
Error in the question.........replace minutes and seconds

YES I AGREE THAT THERE SHOULD BE SECONDS IN PLACE OF MINUTES
Even Usain Bolt does somewhere around 10m/s
I didn't even answer this question because I didn't wanna risk my rating for the wrong question such this.
This means the workers are running at a speed of 90 kmph ha ha ha ha stupid question
they must be on moon,
1 inch in map is equivalent to 500 m in real, so 0.25 inch in map is equivalent to = 5 0 0 × 0 . 2 5 = 1 2 5 m
Now, speed of worker = 2 5 m/min
So, Time = S p e e d D i s t a n c e = 2 5 1 2 5 = 5 m i n
P.S. I think the question is a little bit wrong, the speed should be 25 m/min and not 25 m/s because a person on foot cannot have that much speed. Also then the answer doesn't come right.
if 1 inch = 500 m
0.25 inch = 125 m
speed = 25 m/s
distance = 125 m
time = d/s = 125/25 = 5 sec.
but the question is asking in min. so the answer = 5/60 = 0.8333333.......
there is a error,it should have asked seconds instead of minutes,oh i have wasted 5 minutes coincidentally in thinking out any trick in the question
Because 1 inch is equal to 500 meters, .25 inches would equal 125 meters because .25 inches is 1/4 of 1 inch and 125 meters is 1/4 of 500 meters. To figure out how many minutes it would take for a worker to run from the park to the city hall, you would divide 125 by 25, because it's 25m/s. When you divide the two numbers, your final answer is 5.
I also agree that it should be 25m/m. I was just trying to use the words from the question in my solution.
it should be how many seconds and not in minutes because the unit is m/s
if the scales of the map is 1inch:500m and we know that the distance of the city hall to the park is 1/4inch on the map, so we can find the actual distance by 500/4 = 125m. and then devided 125 by 5 now you got the answer! is 5
This goes too bad since the answer was asked in minutes. We know that Brilliant Mathematics answers were in integers from 0 to 999, but how come a question valued with decimals come into the Brilliant Mathematics?
we know that 1 inch = 500 meters there fore , 0 . 5 1 = x 5 0 0
x= 500*0.25 = 125
we know that speed = t m e d i s t a n c e there fore , speed = 25m/s distance = 125m
time = 2 5 1 2 5
time = 5sec
The scale is 1 i n c h : 5 0 0 m . And since the distance on the map is 0.25 inch, then its real distance is 1 i n c h 5 0 0 m × 0 . 2 5 i n c h = 1 2 5 m . Finally by velocity formula we get T i m e = 2 5 m / s 1 2 5 m
= 5 s
What kind of worker that can run at speed 25m/s??

Ehm, this doesn't make sense. But I've just realized it from your comment
You meant for how many seconds.
