Question

A scale on a map shows that 2.52.52, point, 5 centimeters represents 151515 kilometers.

What number of actual kilometers are represented by 17.517.517, point, 5 centimeters on the map?

Answer 1

105 km

Explanation:

Written as a proportion, the ratio of km to cm will be the same for both distances:

(x km)/(17.5 cm) = (15 km)/(2.5 cm)

x km = (15 km)(17.5/2.5) = 105 km

105 actual kilometers are represented by 17.5 cm on the map.
