B) 68 miles per hour

C) 54 miles per hour

D) 73 miles per hour

E) None of the above

Answer 1

Answer:

B.) 68 mph.

Step-by-step explanation:

First, write this as a ratio>>> 225 feet : 2.26 seconds

Then, figure out how many feet are in one mile>>>  5280 feet

Then, figure out how many seconds are in one hour>>> 3600 seconds

Now, convert your feet to miles>>> 225ft/ 5280mi = 0.04261mi

So, now we know that the cheetah runs 0.043 miles in 2.26 seconds

And we know that there are 3600 second in one hour, so 3600sec/ 2.26sec = 1592.92 seconds.

Now you multiply this by the miles in 2.26 seconds>>> 1592.92* 0.043 = 68.495

So, the cheetah runs approximately 68 mph.
