Question

Mo farah won the 10,000 meter race in the 2012 olympics with an official time of 27 minutes, 30.42 s. to the correct number of significant figures, what was farah’s average speed in m/sec?

Answer 1

Speed = Distance / Time

Distance = 10 000 m
time = 27 minutes 30.42 seconds.

27 minutes = 27*60 seconds = 1620 seconds

time = 27 minutes 30.42 seconds = 1620 seconds + 30.42 seconds = 1650.42 seconds

Speed = 10000 m / 1650.42s ≈ 6.059 m/s

Average speed ≈ 6.059 m/s

Hope this helps.
