A car travels from point A to Be in 3 hours and returns back to point A in 5 hours .Points A and B are 150 miles apart along straight highway .Find the average velocity for A to B ,B to A and for the entire trip in miles per hour

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,

The average velocity from B to A,

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.

answer: 31, 5556. 952 seconds
