she can rent the boat for 9 hours.

Explanation:

First, let's see how many times can 7 fits into 60. that's 8 so that's 56 dollars she spends. She uses the coupon so now she pays 53 dollars. Now since she has enough she can get another hour in so she pays 7 more so she rents the boat and spends exactly 60 dollars.
