Average Speed in Miles per Hour

Spike VM

Calculate the average speed travelled from a set distance in miles and the time it took to complete the trip. Uses miles for distance and hours, minutes and seconds for time.

Travelling from A to B took 4 hours and 34 minutes, distance travelled, 330 miles.
step one: Change the 34 mins 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 travelled by the amount of time.
330 ÷ 4.57 = 72.2 
The average speed  72.2 miles per hour.
