Answer 1

9514 1404 393

Answer:

35 miles

Explanation:

The relevant relation is ...

distance = speed × time

The total distance the trolley traveled is ...

d = (20 mi/h) × (3.5 h) = 70 mi

The distance is the same in both directions, so the trolley traveled half this distance in one direction.

The trolley traveled 35 miles in one direction.
