Spike VM

Calculate the average speed from a distance in miles and the time it took to complete the distance.

Average Speed from Distance and Time

Distance Traveled in Miles mi
Time hrs mins secs
Decimal Rounding #


Miles per Hour mi/hr
Kilometres per Hour km/hr


  1. enter the distance in miles
  2. time of trip in hours, minutes and seconds
  3. number of digits after the decimal point for the results


  1. the average speed in miles per hour
  2. the average speed kilometres per hour


average speed = distance/time

Example Calculation

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)
