Answer:

Average speed of jogger,s=72.46 m/min

Explanation:

Total distance covered by a body divided by the elapsed time to cover that distance is known as average speed of that body.

We have given length of track=100m

Therefore total distance covered by the jogger,

$d=100m+100m\\d=200m$

Total time taken by joggers to cover 200m distace,

$t=1.13 min+1.63m$

t=2.76 min

Therefore average speed of jogger,

$s=\frac{d}{t}$ ...............(1)

put values of d and t in equation 1

we got,

$s=\frac{200 m}{2.76 min}$

average speed of jogger,s=72.46 m/min
