distance time average speed
calculate equation
To calculate average speed, you need the
following equation:
distance
average speed
time
Example
Distance: a lap was 300 metres long.
4 x 300 metres = 1,200 metres
Time: Adams completed the 1,200 metres
in 63 seconds
1,200 19.05 metres
So, average speed:
63 per second (m/s)
To calculate average speed in kilometres
per hour, use this equation:
Average speed in metres per second (m/s)
x 3.6 = average speed in kilometres per hour
(km/h)
1 Look again at the table in exercise 1.
Calculate the average speed of Gollob, Olsen
and Crump, in m/s.
2 Now calculate the average speed of all the
riders in km/h.​
