Plug the distance into the formula. To get elapsed time t t divide total distance by speed. D t D t.
For example A car travels 3 hours.
For example A car travels 3 hours. As it moves further down the ramp its speed changes due to acceleration. If we want to find the average speed for the whole journey of three hours we have to find the ratio between the total distance covered and total time taken. Average speed formula is used to find the uniform rate which involves something travelling at fixed and steady pace.
