Question 13247
You need to figure out first how far each animal would travel in one minute.  To do this, divide each speed by 60 (because there are 60 minutes in 1 hour).  Then, you get that the cheetah travels 1.17 miles in one minute.  The greyhound would travel 0.65 miles in 1 minute.  Then, subtract to get 0.52 miles.  To get the answer in feet, simply multiply by 5280 (because there are 5280 feet in 1 mile) to get 2,745.6 feet.
