The average rate per minute is c but how do we get the answer?

Ok!
    So, if there are 5,280 feet in a mile, and you're going 12 mile per hour, you multiply the feet in a mile by 12 to get how many feet you are traveling per hour. you need to find out in minutes, so all you do is divide that number by 60 because there are 60 minutes in an hour.

Hope this helps!
