Answer:

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

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.

$s=\frac{d}{t}$

The cheetah ran 112 meters in 4 seconds.

d= 112 m
t= 4 s

Substitute the values into the formula.

$s=\frac{112 \ m}{ 4\ s}$

Divide.

$s= 28 \ m/s$

The cheetah's speed is <u>28 meters per second</u> and <u>choice B</u> is correct.
