A white-tailed deer can sprint at speeds up to 30 miles per hour. American bison can run at speeds up to 3,520 feet per minute. Which animal is faster and by how many miles per hour? There are 5,280 feet in one mile. A deer is 10 miles per hour faster than a bison. A bison is 10 miles per hour faster than a deer. A deer is 0.66 miles per hour faster than a bison. A bison is 0.66 miles per hour faster than a deer.

This is a conversion problem, since the answer choices are in miles per hour you want to first convert the speed of American Bison to mph

to get to mph from 3520 feet per minute you want to first divide 3520 by 5280 (because that is how many feet are in a mile) to get it into miles per minute. Then you want to take that number and multiply by 60 (because that is how many minutes are in an hour) to get into mph. Now you have the speed of American bison in mph. You want to subtract the 2 speeds and see which answer choice matches

r u set now?
