Question

If a cheetah runs for 4 seconds and runs 120 meters, how many seconds does it take a cheetah to run 270 meters? Explanation Please

Answer 1

The cheetah needs 9 seconds to run 270 meters

Explanation:

Proportions

Given the rate of change of the distance traveled by a cheetah is constant, we can predict the time taken to travel any distance.

The cheetah runs 120 for 4 seconds. The rate of change is:

`(120\ m)/(4\ s)=30\ m/s`

This is the cheetah's speed.

To run 270 meters, we divide the distance by the speed to find the time:

`t=(270)/(30)=9`

The cheetah needs 9 seconds to run 270 meters
