Question

A runner ran the marathon (approximately 42.0 km) in 2 hours and 57 min. What is the average speed of the runner in m/s?

Answer 1

Ответ:

The average speed of the runner in m/s is 14.31 m/s. This is calculated by dividing the total distance of 42.0 km (or 42,000 m) by the total time of 177 minutes (or 10,620 seconds), giving a result of 42,000 m/10,620 s, which equals 14.31 m/s.
