The answer is 115.
One hour is 60 minutes, so two hours would be 120 minutes.
We know the person is driving 65 mph in one hour. Keeping the same rate, the person would drive 130 miles in two hours.
BUT...
San Diego isn't 130 miles away, it is 125 miles away.
So, the person cannot drive two whole hours to get there since he would past a 125 miles.
He would ALMOST drive two whole hours (120 minutes) though, so the answer would be 115 minutes.
There's another way to solve this problem, but this is more intuitive, in my opinion. Anyways, good luck, and if you have anymore questions then ask me.
