D. The greatest a can be is 9 and the greatest b can be is 4. a+b= 13 which is less than 20
To make this a little easier, you would want to turn 3/4 into 9/12, to match 5/12's denominator.
You would then just add 7/1 to both fractions
(5/12+7/1=12/12 or 1 minutes)
(9/12+7/1=16/12=1 1/3)
So your answer would be 1.333... miles per minute
