Answer: A giraffe can run 26.5mph
Step-by-step explanation:
12 times 60 (seconds) times 60 (minutes) = 43200. This is the total number of meters traveled in an hour. You would divide this by 1609 to get the total number of miles per hour.

It’s server salary = 20(years) * 26710 (annual salary)
Nurse salary = 20(years) * 41980 (annual salary)
Server = 534200
Nurse = 839600
So to find difference = 839600-534200 = 305500 so answer D
