Answer:
A. [tex]\frac{\frac{1}{4} mile }{22.5 seconds} = 40 mph[/tex]
Step-by-step explanation:
Miles per hour can be written like this:
[tex]MPH=\frac{miles}{hour}[/tex]
So, the correct way to write this question would be:
[tex]\frac{\frac{1}{4} mile }{22.5 seconds} = 40 mph[/tex]
If you multiply 22.5 by 4 you get 90, which is 1.5 minutes.
So, a hyena can run a mile in 1.5 minutes.
Divide 60 by 1.5 and you find that the hyena runs 40 miles in 1 hour.
It can't be 90mph. The hyena can't run 60mph because it doesn't run a mile a minute.
Therefore, your answer is A.
I hope this helps!!
