Question

The top speed of a cheetah is approximately 1.2 × 10^2 kilometers per hour, while the speed of the fastest human is approximately 4 × 10^1 kilometers per hours. How many times faster is the top speed of a cheetah than the speed of a human?
Pls help!!

Answer 1

If we convert the scientific notations to standard form it will be: Cheetah: 1.2 x 10^2 = 120 Human: 4 x 10^1 = 40

Now that it’s more simple visually, we can do 120/40 = 3

A cheetah is 3 times faster that a human.
