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:
[tex]\frac{120\ m}{4\ s}=30\ m/s[/tex]
This is the cheetah's speed.
To run 270 meters, we divide the distance by the speed to find the time:
[tex]t=\frac{270}{30}=9[/tex]
The cheetah needs 9 seconds to run 270 meters
