Answer:
Required distance is 5843.5m and displacement is 120m
Explanation:
Given, radius of circular path=60m
Time taken for one round to complete=20seconds
Total time given is 5 min 10sec=5×60+10=310
Now, distance covered in 1 round is 2πr=2π×60
Hence total number of round is 310/20 i.e.15 and 1/2
So, total distance is 15×2π×60+1/2 ×2π×60 = 5843.5m
And displacement is 2r=2×60=120m
