Answer:B

15 Miles per hour

Step-by-step explanation:

Step one: find out how many times 12 goes into 60 (because 12 is the amount of minutes it took to go 3 miles, and one hour is 60 minutes.)

Step two: 12 goes into 60 by five so you have to multiply the three times five as well.(look at step three for more info.)

Step three: 3 miles times 5
