Step-by-step explanation:

Given that,

The time taken from A to B is 3 hours

The time from B to A = 5 hours

The total distance between A and B is 150 miles

The average velocity from A to B,


v=(150)/(3)=50\ mph

The average velocity from B to A,


v=(150)/(5)=30\ mph

As the velocity of an object is a vector quantity. It means when the car reaches the initial point, the displacement is 0. So, the average velocity is equal to 0.
