Question

George walks to a friend's house. He walks 750 meters North, then realizes he walked

too far. He turns around and walks 250 meters South. The entire walk takes him 13
seconds.

Answer 1

I think you are looking for the velocity, so the answer is 38.5 m/s

Step-by-step explanation:

Velocity is giving by displacement/time. North will be positive and South will be negative, George travels 750 meters then travels -250 meters his displacement is then 750 - 250 or 500 meters. Divide that by 13 seconds to get 38.5 m/s.
