4. John can travel 560 miles in 9 hours east to New York. What is his velocity?

62.2 mph East

Explanation:

Velocity is the distance moved per unit time with consideration to the direction of movement.

Velocity, v=d/t

Where d is distance and t is duration or time

Substituting 560 miles for distance and 9 hours for time then

V=560/9=62.222222222222 miles per hour

Rounded off to 1 decimal place

V=62.2 mph

The direction is East of New York

Therefore, conclusive velocity is 62.2 mph East

answer; /// the above statement is (true);

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
