A distance of 68 km is represented on a map by 1.7 cm. What distance is represented by 8.5 cm on the same map?

KnowledgeBoat · Accepted Answer

Given: Map distance 1.7 cm = Actual distance 68 km Map distance 8.5 cm = ? Let actual distance for 8.5 cm = x km Ratio of map distances : Ratio of actual distances 1.7 : 8.5 :: 68 : x By the rule: Product of Extremes = Product of Means: 1.7 x x = 8.5 x 68 ⇒ x = ⇒ x = 5 x 68 ⇒ x = 340 Hence, the distance represented is 340 km.
