Calculate the average speed from a distance in miles and the time it took to complete the distance.
average speed = distance/time
Step one: Change the 34 minutes into an hourly value. one minute = 0.01667
0.01666667 * 34 = 0.57 (rounded to two digits)
time of trip in hours = 4 + 0.57 = 4.57 hrs
Step two: divide the distance traveled by the amount of time.
330 ÷ 4.57 = 72.2
The average speed 72.2 miles per hour.
one hour = 60 minutes one minute = 0.01666666666666666666666666666667 hours one mile (mi) = 1.609344 kilometres (km)
