Cheetahs are the fastest land animals; they can run up to 70 mph and weigh about 100 pounds on average. An average human weighs 137 pounds. If humans had the same ratio of speed to weight as a cheetah, how fast could we run?

By calculating the speed-weight ratio of a cheetah and applying it to the average human weight, we find that humans could potentially run at 95.9 mph if they had the same ratio of speed to weight as a cheetah.

Explanation:

If we want to calculate how fast a human could run if they had the same ratio of speed to weight as a cheetah, first, we need to determine the ratio for the cheetah.

A cheetah can run up to 70 mph and weighs about 100 pounds on average. Thus, the ratio of speed to weight for a cheetah is 0.7 mph per pound (70 mph / 100 pounds).

Next, we apply this ratio to the average human weight. An average human weighs 137 pounds. Using the cheetah's speed-weight ratio, we multiply 0.7 mph by 137 pounds to find the hypothetical human speed.

This equals 95.9 mph. So, if humans had the same ratio of speed to weight as a cheetah, they could run 95.9 mph.
