Answer 2

A. 32 miles

Explanation:

The shortest route from the middle school to the airport is via City Hall and the high school. Returning by the same route lets Mary drop her father at City Hall as required. The total map distance is ...

2(21 cm +12 cm +15 cm) = 2(48 cm) = 96 cm

At a scale of 3 cm per mile, that distance represents ...

(96 cm)/(3 cm/mi) = 32 mi

Mary traveled 32 miles.
