Question

A runner runs 10,000 meters in 20.13 minutes. What was the runner's average speed in miles per hour? Report your answer in standard form (not scientific form).

Answer 1

21.13 minutes = 20.13/60 hours = .3355 hours

1 km =0.69344498 miles

10,000 meters = 10 km

10 km = 6.9344498 miles

6.9344498 miles per 0.3355 hours

= 6.9344498/0.3355 = 20.66900089 mph

10,000 meters per 20.31 minutes = about 20.7 miles per hour

10k per 20.31 min = about 20.7 mph

(26.24 minutes is the world record for a 10k race. so 20.7 mph is faster than the world record)
