Question 68203: Ching leaves San Francisco and travels toward Los Angeles at 50 mi/h. An hour later, Phil leaves Los Angeles and travels toward San Francisco at 60 mi/h. If the two cities are 380 miles apart, how many hours will it take for Ching to meet Phil?

At the start, the total distance between the two was 380:
380
Then, Ching drives for 50 miles for 50mi/h:
330 - 50x
Then, Phil travels 60 mi/h:
330 - 50x - 60x = 0
-110x = -330
x = 3
3 hours
