The cheetah and the gazelle have something in common.
To survive, they each must run faster than the nearest gazelle.

The cheetah is the fastest land animal, and since it is a cat, it is carnivorous and must hunt and kill to survive. In the area of the world where the cheetah lives, there are many gazelles, so gazelles are a common prey of cheetahs. Even though gazelles are also very fast runners, they are not as fast as cheetahs, especially in a straight line, and yet, many times, they easily escape the cheetahs.
