Average Speed in Kilometres per Hour

Spike VM

Calculate the average speed from a distance traveled in kilometres and the time it took to complete the trip.

Average Speed from Distance and Time

Distance Traveled in Kilometres km
Time hrs mins secs
Decimal Rounding #


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


  1. enter the distance in kilometres
  2. the time it took to travel the distance in hours, minutes and seconds
  3. number of digits after the decimal point for the results


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


speed = distance/time

Example Calculation

distance travelled = 344.4 kilometres
travel time = 3 hours and 24 minutes

Step one: change the 24 minutes into an hourly value.
24 ÷ 60  = 0.4 
3 + 0.4 = 3.4 hours
Time of trip in hours = 4 +  0.57 = 4.57 hrs.

Step two: divide the distance travelled by the amount of time
344.4 ÷ 3.4= 101.29
The average speed  101.29 kilometres per hour.


one hour = 60 minutes
one minute = 0.01666666666666666666666666666667 hours
one kilometre (km) = 0.621371192237334 miles (mi)
