The time taken by Rohan in five different races to run a distance of 500 m was 3.20 minutes, 3.37 minutes, 3.29 minutes, 3.17 minutes and 3.32 minutes. Find the average time taken by him in the races.

= (3.20 +3.37 +3.29 +3.17 +3.32] minutes

= 16.35 minutes

Total number of races = 5

∴ The average time taken by Rohan

= 16.35/5 minutes

= 3.27 minutes.
