Option 1​

Answer 1

Answer:

Here is your answer.

Explanation:

Answer 2

The average speed of the car is (Va+v)/2.

Given,

The speed of the car in the first interval is Va And the speed of the car in the second interval is v.

To find,

The average speed.

Solution,

We know,

To find the average is to find the mean.

To find the mean/ average, we have to divide the sum of all outcomes by the number of outcomes.

In this question,

the average speed= (Speed in the first interval+ Speed in the second interval)/2.

=(Va+v)/2.

So, The average speed of the car is (Va+v)/2.
