Best Answer

To convert the time from minutes to hours, divide by 60, since there are 60 minutes in an hour.

42 minutes ÷ 60 = 0.7 hours

To find the speed in miles per hour, divide the distance by the time.

3 miles ÷ 0.7 hours = 4.29 miles per hour

Therefore, 3 miles in 42 minutes is approximately 4.29 miles per hour.
