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.
None. Hours is a measure of time while miles is a measure of distance. The two measure entirely different things and you cannot convert one to the other with out additional information. Are you travelling at the speed of a snail or a light beam, for example?
Divide the number of miles by the number of hours to obtain the unit rate. You should get: 128 miles / 2 hours = 64 miles per hour
