Step-by-step explanation:
The LCM(12, 20) = 60.
Selection B is appropriate.
_____
It takes 12 times as long to fill the whole tank as it does to fill 1/12 of the tank.
.. 12 * (1/3 hour) = (1/3)*12 hour
1 hour = 60 minutes, so 3 hours = 3 * 60 = 180 minutes.
Her total time was 3 hours and 28 minutes, so 180 + 28 = 208 minutes.
Divide her total time by total miles run:
208 minutes / 26 miles = 8 minutes per mile.
