Question

An athlete takes 33 minutes and 50 seconds to run 10 000 m.

Work out the athlete’s average speed in kilometres/hour (round to 3sf).

Answer 1

Answer: 17.9 km/h

Explanation:

Convert 33 minutes and 50 seconds to Hours:

= 33 ⁵⁰/₆₀ minutes

= 33.83 minutes

In hours that would be:

= 33.83 / 60

= 0.56 hours

10,000 meters in kilometers is:

= 10,000 / 1,000

= 10 kilometers

Speed = 10 / 0.56

= 17.9 km/h
