Answer:
40 miles per hour
Step-by-step explanation:
If we know the distance someone or something ran and how long it took them to run, then we know their rate.
Because rate can be defined as .
We want the answer to be in miles per hour, so convert 22.5 seconds into hours by dividing 22.5 by 3600.
22.5 / 3600 = 0.00625
And because we have a decimal and a fraction, it is best to convert the fraction into a decimal so all units are the same.
1 / 4 = 0.25
Plug in the values.
0.25 / 0.00625 = 40
So, the hyena would be running at 40 mph.
