A highway and a train track run parallel to each other. At 5:00 a train crosses a river. Fifteen minutes later, a car, traveling in the same dirrection, crosses the river. The train's average speed is 52mph, the car's is 64mph. When will the car pass the train? 15 minutes = 1/4hour, so train traveling 52mph is 13 miles away from the car over the river. 64 - 52 = The vehicles are converging at a rate of 12mph. From D = RT, T = D/R. So, T = 13/12 13/12 = 1 and 1/12th of an hour, or 65 minutes. The car should pass the train in 01:05, or at 6:05. This answer is not listed among the choices. WTF???
