A car moves at a uniform velocity and travels 240 kilometers in three hours. If the car continues at the same velocity, what distance will be covered in five hours?

Average speed is equal to the distance travelled divided by the time taken. So the car moved 240 kilometers in three hours, so 240 divided by three is 80. So they must have been going 80 kilometers per hour, so per one hour. So if we take this same equation and the average speed we plug in, 80, the distance travelled is what we’re trying to find, and it’s five hours, the time taken. So in order to find this distance travelled, we need to multiply both sides of the equation by five. And 80 times five is 400.

So if the car is moving 80 kilometers per hour, then it would cover a distance of 400 kilometers in the five hours.
