Question

find the average speed of bicycle if it completes 2 round of a circular track of radius 140 metre quiz in 5 minute 52 second​

Answer 1

radius of track=140metre

as it completed 2 rounds of the circular track.. then the area covered by bicycle will be the circumference of the circle..

circumference of the circle=2×pie×r

=2×22/7×140

=880metres

as the bicycle covered 2 rounds of the track.. then area covered by bicycle will be 2×880= 1760 metres

so...

total distance=1760metres

total time=5 minutes 52secs = 352secs.

speed = distance/time

avg speed= total distance/total time

avg speed = 1760/352

avg speed = 5 m/sec..

i hope the answer is correct and satisfies u..
