Question

Jonathan can jog miles in 3 2/5 miles in 6/7 hour. Find his average speed in miles per hour.

Answer 1

about 4 mph

Explanation:

there are 60 min in an hour

60 ÷ 7 = about 51

so 6/7 of an hour is about 51 min

so Jonathan can jog 3 2/5 miles in about 51 min

3 2/5 ÷ 51 = 1/15

1/15 × 60 = 4

so the answer is about 4 miles per hour
