Question

The scale of a road map indicates that 4 cm is equal to 30 km. Calculate the distance in km between two cities if the road between them is 10 cm long.

Answer 1

The road map indicates that 4 cm in its scale is equal to 30 km. Each cm indicated on the map would be 30/4 = 7.5 km. As the road between the two cities on the map is 10 cm long, 7.5 x 10 = 75 km.
