Question

a car covers100 m distance in 12 sec and covers next 50m in 3 sec. Find the average speed of the car.​

Answer 1

Answer:

The average speed of the car is 10 m/s.

Explanation:

The average speed of an object can be calculated using the equation,

Average speed = total distance / total time taken

The car covers 100 m in 12 seconds and 50 m in the next 3 seconds.

So the total distance covered by the car = 100 + 50 = 150 m

Total time taken to cover this distance = 12 + 3 = 15 s

∴ Average speed = 150 / 15

                             = 10 m/s
