George walks to a friend's house. He walks 850 meters north before he realizes he walked too far. He turns around and walks 250 meters south. The entire walk takes 25 seconds. What is George's
velocity in m/s?

Explanation:

In this problem we are expected to calculate the velocity of Georges movements.

Given data

Total distance covered by  George= 850+250= 1100 meters

Time taken  by  George to cover the total distance= 25 seconds

We know that velocity is, v= distance/ time

Therefore substituting our data into the expression for velocity we have

v= 1100/ 25= 44 m/s

Hence the velocity in m/s is 44

where's the following? you gotta add it to know what the choices are

explanation:

force tends to be low and long diustance masses are high
