You can put this solution on YOUR website!
The distance across the diagonal is greater than 15 yards.
The diagonal = sqrt%2815%5E2+%2B+12%5E2%29
= sqrt%28369%29
=~ 19.2 yards
--------------
It's stated that she can turn it off from 15 yards, or "up to" 15 yards. It does not say that 15 yards is the maximum, or "up to but not exceeding", so whether or not it will work from 19.2 yards is not known.

Another example of a poorly worded problem.
