Answer 2

The average speed of the car is 40 km//h.​

Given:

The distance between Ahmedabad and Vadodara is 100km. A man drove his car from Vadodara to Ahmedabad in 2 1/2 hours.

To find:

Calculate the average speed of the car.​

Solution:

To find the average speed, we have to find the speed of the car

We have distance as 100 km and time as 2 1/2 hrs = 5/2 hrs and we will apply the formula to calculate speed

Speed = Distance/time

= 100/(5/2)

= 100*2 / 5

= 20*2

= 40 km/hr

Hence, the answer is 40 km/h.
