Question

a man runs 650 m east and then turns and runs 850 m west. this takes him 240 seconds. what is the distance covered by the man?

Answer 1

v = 6.25 m/s Explanation:
Given that,
A man runs 650 m east and then turns and runs 850 m west. This takes him 240 seconds.
Let east is positive and west is negative
Average velocity = total displacement/total time taken
Total displacement = final psoition - initial position
D = -850 - 650 = -1500 m
So,
