Answer
Given: a distance of 68 km is represented by 1.7 cm.
to find: the distance represented by 8.5 cm on the same map.
Step-by-step explanation:
on setting up a proportion, i.e direct variation, we get,
68 km :1.7 cm:: x km: 8.5 cm
using the formula: the product of means= the product of extremes,
= 68*8.5=1.7*x
⇒ 68*8.5/1.7= 340 km
⇒ a distance of 340 km is represented by 8.5 cm on the same map, using the same scale.
