Answer:B

15 Miles per hour

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

----------------------

12 minutes times 5

equals |

V

15 miles

-------------

60 minutes/ 1 hour

The answer would be “b”: 15 miles per hour.
Explanation: divide 12/3 get 4. That would be the pace per mile 4:00 minutes. Then the speed would be .25 miles per min which is equal to 15 miles per hour
