Question

a farmer has to go 500 m due north, 400 m due east and 200 m due south to reach his field. If he takes 20 min to reach the field, what is the average velocity of farmer during the walk ? (A) 35 m/min. (B) 45 m/min. (C) 25 m/min.

Answer 1

Answer:

(C) 25 m/min

Explanation:

By the defInition of velocity, it is displacement per unit time.

I have provided a picture plotting the path followed by the farmer.

If you observe a right angle is formed, and by using pythagoras theorem we come to know that the displacement is 500 m

Since he takes 20 min to cover a displacement of 500 m, his velocity is 500/20 = 25 m/min.
