Question

Alex is running around a circular path with a circumference of 300 m. He runs two complete rounds
in 3 minutes each, and on the third round, he stops midway in 1.5 minutes as he feels tired. Find his
average speed and average velocity in m/s​

Answer 1

Answer:

Radius of lap = 100m

Circumference =2πR=200π=628m

time taken to cover one lap = 62.8s

Hence average speed =

62.8

628

=10ms

−1

Average velocity = 0 as the inital and final positions are same (after completing a lap) (displacement = 0)

Hence option B is correct.

Answer 2

this is the answer of the above mentioned
