Find the average speed of bicycle if it completes two rounds of a circular track of radius 140 m twice in 5 mins 52 sec

Answer 1

Answer:

Radius = 140m

Circumference = 2πr = 2 × 22/7 × 140 = 44 × 20 = 880 sq.m

Time = 5 min. 52 sec. = 5 × 60 + 52 = 300 + 52 = 352 sec.

Average Speed = Total Distance / Total Time

Average Speed = 880 / 352 = 2.5 m/s
