It is essential that you use the symbol " ^ " to denote exponention. See the following changes I have made.
9u^2v and which term or terms are like terms? 15u^2v. Why? because both have "u^2" in them.
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
Hope this helps
