Your calculation of George's SPEED is correct. Nice work !

Velocity is different. Here's how to do velocity:

Velocity = (displacement) / (time)

Displacement = (distance and direction from start-point to end-point)

George ended 500 meters North of where he started. So his displacement is 500 meters North.

Velocity = (500 meters North) / (13 seconds)

Velocity = 38.46 m/s North

Answer:


v = 38.46 m/s

Step-by-step explanation:

As we know that velocity is defined as the ratio of total displacement of the object and total time taken by it

So here we know that


v = (d)/(t)

here we have

d = 750 (North) + 250 (South) m


d = 750 - 250 m


d = 500 m North

time taken by him is given as


t = 13 s

now we have


v = (500)/(13)


v = 38.46 m/s
