Distance=circumference
Circumference=2πr
=2 × 22/7×105
=660 mtrs
Time= 5mins OR 5X60=300 sec
Speed= d/t
s=660/300 m/s
s=2.2mtrs/second.
I hope it was helpful.

Answer:
To calculate the speed, you have to make use of the formula and it gave diameter and speed
Given:
Diameter is 105 m
Radius: 52.5 m
Circumference will be
2x22=44
=44/7
= 6.2
=6.2 x52.5
= 330 m
Time is 5 min
=5x60- 3000 seconds
Formula:
Speed=distance based on time =330/300
=1.1m/s
