Mary left the hardware store and traveled toward her cabin on the lake at an average speed of 52 mph. Stefan left one hour later and traveled in the same direction but with an average speed of 65 mph. How long did Mary travel before Stefan caught up?
------------
In 1 hour, Mary is 52 miles ahead.
Stefan gains on her at 13 mi/hr (65 - 52)
52/13 = 4 hours to catch up --> Mary drove 5 hours.
==================
This works if the cabin is >= 260 miles away.
If it's closer they would just meet there.
