Question

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?

Answer 1

Convert 3520 feet per minute to miles per hour.

Here are the necessary conversions needed:
5280 feet = 1 mile
60 minutes = 1 hour

You can either use
5280 ft/ 1 mile OR 1 mile/ 5280 feet
to change from feet to miles?

Which one do you think it is? Remember, the units should cancel for feet and you should be left with miles in the numerator.

Similarly for minutes and hours, you have
60 minutes/ 1 hour OR 1 hour/ 60 minutes
Which one will you use?
