Question

. Rahim walks along a footpath of 180m long . he covers 360m in one

minute by walking from one end to the other end and back along the

same straight path. find the average speed and average velocity of rahim​

Answer 1

TOTAL DISTANCE COVERED BY RAHIM FROM ONE END AND BACK ALONG THE SAME STRAIGHT PATH

=360+360=720m

TIME TAKEN =1×60=60sec

$avg \: speed = \frac{total \: distance}{time} \\ avg \: speed = \frac{720}{60} = 120 \frac{m}{s}$

TOTAL DISPLACEMENT IS ZERO AS INITIAL AND FINAL POSITION IS THE SAME

TIME TAKEN=60sec

$avg \: velocity = \frac{total \: displacemet}{time} \\ avg \: velocity = 0$

i hope this helps ( ╹▽╹ )
