Question

The scale of a map is 1:5000000.what is the actual distance between two town s,if they are 4cm apart on the map?

Answer 1

the distance is 20000000cm or 2km

Answer 2

let x be the ground distance for a map distance of 4 cm

1:5000000 means that a map distance of 1 cm corresponds to a ground distance of 5000000cm

1:5000000 = 4/x
x = 4 x 5000000
x = 20000000 cm
= 2Km
