Katie wants to know how fast she is riding her bike. She travels 10km in 60 minutes, what is her speed to the nearest decimal place (in m/s)?
60 x 60 = 1200 (to work out the time in seconds)10 x 1000 = 10000 (to work out the distance in metres)
speed=distance divided by time10000 divided by 1200 = 8.3333...
Therefore, Katie is going at a speed of 8.3m/s
