to get from point a to point b it take 644 miles you travel this distance in 2 hours what is your velocity

just do 644 divided by 2 then there is your answer so what is

644/2 = which is 322 there is your answer

your average SPEED = 644/2 = 322

I can not say what your velocity is. Velocity is a VECTOR and
you must know the direction
for example
The answer could be zero if you went North 322 miles and then back South 322 miles.

thanks

You can read your speed on a speedometer. However for velocity you also need a compass :)

You are welcome.

no compass needed. The velocity is in the direction from A to B, of course!

B could be right beside A, out and back :)
