Question

If you run a 10 kilometer race in 42 minutes 42 seconds, what is your average pace (time per mile in minutes and seconds)? what is your average speed in miles per hour?

Answer 1

Solution:

Average Pace = 0.621371 mile

10 km = 6.21371 mile

42 min 42 sec = 42.7 min

Average pace = $\frac{42.7}{6.21371}  =  6.8719$ minute/mile

42 minutes 42 seconds = 2520 + 42 = 2562 sec

Average pace = $\frac{2562}{6.21371} = 412.314$

Also, 42 min 42 sec = 0.7116 hour

Average speed = $\frac{6.21371}{0.7116} = 8.732 mile/hour$

Hence, the average speed is 8.732 mile/hour
