I need to set up this problem algebraically. Also I can't figure out to work it out. It's a relative rate problem.

Bob leaves Bismarck traveling east along Interstate 94 at 65 mph. At the same time Tony leaves Fargo traveling west on Interstate 94. Since he is pulling a trailer, he can go only 45 mph. Fargo is 193 east of Bismarck. How long will it be until they meet?
