Question

A bus starts from town A and reaches town B with speed 40km/h. It returns to town A with speed 60km/h.
The average velocity of the bus is?​

Answer 1

Answer:

0 m/s

Explanation:

Since the bus returned to the starting point, the net distance travelled is 0m. So velocity will also be 0

Answer 2

Zero is the average velocity of the bus.

Given,

Speed of the bus in two cases = 40km/h and 60km/h.

To Find,

The average velocity of the bus.

Solution,

Given that,

The bus travels from A to B at a speed of 40km/h.

The bus returns from B to A at a speed of 60km/h.

We need to find out the average velocity.

Average velocity = $\frac{Total Displacement}{Total Time}$

Here the bus travels to town B and then it returns to its starting point.

So the total displacement is zero in this case.

Hence, the average velocity of the bus is zero.
