In the country of Mu, two towns, Alpha and Theta are in the same time zone. They are connected by a highway 200 miles long. A bus leaves Alpha at 3:00 p.m. and travels at a uniform rate of 50 mph toward Theta. 12 minutes later, a second bus leaves Alpha and travels toward Theta at a uniform rate of 55 mph. At what time (p.m.) will the second bus catch up to the first bus?
