Answer :
Radius of circular track = 14 m
Circumference of circular track = 2πr
= 2 × 22 / 7 × 14
= 2 × 22 × 2
= 44 × 2 = 88 m
Speed of athletes = 11 m / s
Time taken = distance / speed
= 88 / 11
= 8 sec
Radius of circular track = 14 m
Circumference of circular track = 2πr
= 2 × 22 / 7 × 14
= 2 × 22 × 2
= 44 × 2 = 88 m
Speed of athletes = 11 m / s
Time taken = distance / speed
= 88 / 11
= 8 sec
