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?

Speed=distance/time

distance = 10,000 m

time = 27 min 30.42s but we need to convert that completely to seconds

(27x60) + 30.42 = 1650.12 rounded to 1650

speed=10,000/1650.12

speed=6.059063

Because when we do sig dig we round to the least number of digits we would round to 4 because 1650.12 gets rounded to 1650

so 6.059 m/s
