Question

A map is given with a scale of 2cm = 100km.what is the actual distance between the two places in kms,if the distance in the map is 2.5cm?

Answer 1

Scale = 2 cm = 100 km

1 cm = 100/2 = 50 km

2.5 cm = 2.5 * 50 = 125 km

the actual distance between the two places is 125 km

Answer 2

Let the distance be x km

Then, x : 1000 = 2.5 :2

= x = 2.5

1000 2

x = 2.5 × 1000

2

Therefore, x = 1250
