A man runs 650 m east and then turns and runs 850 m west. This takes him 240 seconds. What is the man’s average VELOCITY for the race?

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,

So, 6.25 m/s is the average velocity of the man.

i don't know that i agree with that but what's the question ?

your answer is c! hope this : )
