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

Answer:

Given data,

Distance ran in Km = 10 km

Distance ran in miles = 10/1.609 (since 1 mile = 1.609 Km)

Distance ran in miles = 6.214 mile

Time to run in sec = 42*60+42 = 2562 sec

Average speed in mile/sec = 6.214/2562 = 0.00245 mile/sec

Time to run in min = 42 + 42/60 = 42.7 mins

Average speed in mile/min = 6.214/42.7 = 0.1455 mile/min
