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,

$v=\dfrac{150}{3}=50\ mph$

The average velocity from B to A,

$v=\dfrac{150}{5}=30\ mph$

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.
