Question

A man is walking on the boundary of his square farm whose side is 100 m long. It takes him 6
minutes to complete one round. Find his average speed and average velocity when he has
completed (i) 1/4th round , (ii) ½ round , (iii) 3/4th round.

Answer 1

Answer:

Average Velocity:

$V_{average} = \overline{v} = \frac{x_{2}-x_{1}}{t_{2}-t_{1}} = \frac{\Delta x}{\Delta t}$  

Average Speed:

$v = \frac{d}{\Delta t}$

Total distance walked (square): 400 m

t = 6 min = 360 s

$\overline{v} = \frac{400}{360} = 1.11 m/s$

$v = \frac{400}{360} = 1.11 m/s$
