I need help with a word problem involving a U.S. customary length conversion

Question

Jim drove 12  laps on a race track. If each lap of the track was 5860.8yd  long, what was the total distance he drove? Write your answer in miles.

Answer 1

First, (5860.8 yards) × (12) = 70,329.6 yards

Next, since there are 1760 yards in a mile, each yard is 1/1760 of a mile. So multiply the total yards by 1/1760 to convert yards to miles:

(70,329.6 yards) × (1/1760 miles/yard) = ____ miles
