Question

Mia’s house and her aunt’s house are 15.4 inches apart on the map. If every 4 inches on the map represents 10 miles, what is the actual distance from Mia’s house to her aunt’s house, to the nearest tenth of a mile?
2.6
6.2
38.5
61.6

Answer 1

Scale: 4 in = 10 mi → 1 in = 10/4 = 2.5 mi.
Actual distance = 15.4 in × 2.5 mi/in = 38.5 miles.

Answer: 38.5
