Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 75 miles per hour. The eastbound train travels at 55 miles per hour. How long will it take for the two trains to be 182 miles apart?

Do not do any rounding.

I have no idea where to even start with this problem.
