If the scale of two maps are (a;1:100,000 and b;1:400,000) what is the ground distance if the distance between two towns on the maps is 10cm
map distance = 10cm, ground distance = ?
Map scale for (a) 1:100,000
Ground distance = 10 x 100,000/100,000 =10km
Map scale for (b) 1:400,000
Ground distance = 10 x 400,000/100,000 =40km
