Distance from Speed and Time - Kilometres

Spike VM

Calculate the distance travelled for a given speed measured in kilometres per hour for a set amount of time.

Distance from Speed and Time - Kilometres

Speed in Kilometres/Hour km/hr
Travel Time hr min
Decimal Rounding #


Distance Traveled in Kilometres km
Distance Traveled in Miles mi


  1. enter the speed in kilometres per hour
  2. the time of travel in hours and or minutes
  3. number of digits after the decimal point for the results


  1. the distance traveled in kilometres
  2. the distance traveled in miles


distance = speed * time

Example Calculation

You are travelling at a speed of 126 kilometres per hour (speed and time) for 2 hours and 45 minutes (time).
Both speed/time and time have to be in the same units to make the multiplication.
Changing the 2 hours and 45 minutes into an hour format makes sense.

There are 60 minutes in one hour; to change one minute into hours, divide one by 60.
1 ÷ 60 = 0.01666666666666666666666666666667.
Multiply this amount by 45;
0.01666666666666666666666666666667 * 45 = 0.75
2 hours and 45 minutes = 2.75 hours

Multiply 126 kilometres per hour by2.75 hours to get the distance;
126 * 2.75 = 346.5
At a speed of 126 kilometres per hour for two hours and 45 minutes, you will travel a distance of 346.5 kilometres.


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