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

Answer:

The cheetah needs 9 seconds to run 270 meters

Step-by-step 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:

$\frac{120\ m}{4\ s}=30\ m/s$

This is the cheetah's speed.

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

$t=\frac{270}{30}=9$

The cheetah needs 9 seconds to run 270 meters
