Spike's Calculators

Calculate your average speed in kilometres per hour based on the distance traveled in a specific period.

- enter the distance traveled in kilometres
- the time in hours, minutes and seconds
- number of digits after the decimal point for the results

- the distance traveled converted to miles
- your average speed in kilometres per hour
- the average speed in miles per hour

Speed = distance/time

distance travelled = 154 kilometres the time it took to travel this distance = 7 hours and 12 minutes

Changing the 12 minutes into decimal hour format; There are 60 minutes in one hour; to change one minute into hours, divide one by 60.

1 ÷ 60 = 0.01666666666666666666666666666667.

Multiply the 12 minutes by 0.01666666666666666666666666666667 to covert to a decimal hour.

12 * 0.01666666666666666666666666666667 = 0.2

7 hours and 12 minutes = 7.2 hours

Divide the distance by 7.2 hours to get the kilometre-per-hour speed;

154 ÷ 7.2 = 21.3888 rounded to 21.4

Your average speed of travel in this example is 21.4 kilometres an hour.

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