Nigel and Shawn on a Map

5 km on the ground is represented by 2 cm on the map

Therefore, 1 km is represented by (2/5)cm

15.75 km is represented by (2/5)*15.75 cm = 6.3 cm Ans.

The scale of the map is 2cm:5km

If we make the problem like ratio, it will look like this: (Let x be the answer)

$x:15.75$

We make it like a fraction and cross multiply and get the value of x which will be our answer: 6.3

15.75 is 15 + 0.75 - 15 ÷ 5 =3 - 3 × 2 = 6 - 0.75 ÷ 5 = 0.15 - 0.15 × 2 = 0.3 - Ans is 6 + 0.3 = 6.3

In the map, 2cm= distance of 5km

=>1km=2/5cm

=>15.75km=2/5x15.75cm=6.30cm

Hence they are 6.30cms apart on the map

1km is 2/5cm 15.75. 2/5 is 6.3

6.30 cm

2cm:5km = x cm:15.75km x = [(2cm) (15.75km)] / 5km x = 31.50cm/5 x = 6.30 cm

The ration between them can be written as:

2/5 = x/15.75

Therefore; x = (15.75 × 2) ÷ 5 = 6.3 cm

2:5=x:5 so, x=6.3

5 km on the ground is represented by 2 cm on the map Therefore, 1 km is represented by (2/5)cm 15.75 km is represented by (2/5)*15.75 cm = 6.3 cm Ans.

5 km = 2 cm so, 15.75=?

15.75*(2/5) = 6.3 cm

To be exact the the distance on the paper is 6.34920634921

6.3 cm

15.75 km multiplied by (2cm/5km). cancel out the km units and get 6.3 cm

15.75 / 5=3.15 * 2= 6.3

Let x is the answer.

Simple, you only use the comparison!

2/5 = x/15.75

31.5 = 5x (cross multiplication)

x = 6.3 cm (63E-1) cm

If 5km cover 2 cm on map then, It should be like this

5/2=15.75/x

By cross multiplication

=> 5x=31.5

=> x=31.5/5

=> x=6.3
