    This is the daily schedule that Harry has stuck to on Monday to Friday for the past six weeks whilst working from home. He has always taken Saturdays and Sundays off from work.

    1. He leaves the house at 7 am and returns at exactly 8 am. To the nearest 0.1 m/s, what is his average speed during his 10 km run?
    • 5
    1

    Explanation

    Answer: D

    Explanation: 

    1. Convert the units into metres and seconds and find the average speed.

    1 hour = 60 minutes = 60 x 60 seconds = 3600 s

    10 km = 10,000 m

    So in metres per second:

    10000 / 3600 = 2.777… = 2.8 m/s

    Common trap: Notice that the answers are all in m/s. He has run at 10 km/h so make sure that you don’t slip up and pick answer E without thinking.
