Question

How long will it take Mr. Wu to run 5000 m at an average speed of 10 m/s ? Give your answer in minutes and seconds

Answer 1

500 seconds

8.20 minutes

Answer 2

We have to find the time taken by Mr. Wu to run 5000 m at an average speed of 10 m/s.

solution : we know, speed = distance covered/time taken

so, time taken = distance covered/speed

here average speed of Mr. Wu = 10 m/s

distance covered by Mr Wu = 5000 m

so, time taken by Mr Wu = 5000/10 = 500 sec

we know, 1 min = 60 sec

∴ 500 sec = 500/60 min = 25/3 min

therefore time taken by Mr. Wu is 500 sec or 25/3 min.
