Question

in 4 seconds, a cheetah can run 112 meters. How fast does this cheetah have to be running? A: 448 m/s || B: 28 m/s || C: 56 m/s || D: 36 m/s​

Answer 1

B: 28m/s

Step-by-step explanation:

Use the speed formula

Speed =distance / time

Answer 2

`\boxed {\boxed {\sf B. \ 28 \ m/s}}`

Step-by-step explanation:

If we want to know how fast the cheetah is running, we need to calculate its speed. This is the rate at which an object moves and the formula is distance divided by time.

`s=(d)/(t)`

The cheetah ran 112 meters in 4 seconds.

• d= 112 m
• t= 4 s

Substitute the values into the formula.

`s=(112 \ m)/( 4\ s)`

Divide.

`s= 28 \ m/s`

The cheetah's speed is 28 meters per second and choice B is correct.
