Question

Hodaya is drawing a map of the trails in the canyon near her house. She knows that the distance from the first creek crossing to the second creek crossing is 1.8 miles.

If every 3 inches on the map represents 0.75 of a mile, how far apart will the two creek crossings be on the map, to the nearest tenth of an inch?
2.3
4.1
5.4
7.2

Answer 1

Scale: 3 in = 0.75 mi → 1 mi = 3 / 0.75 = 4 in.
Distance on map = 1.8 mi × 4 in/mi = 7.2 in.

Answer: 7.2
