Two cars start at the same time from two places 330 km. apart and travel toward each other.Car A travels at 50 kph and Car B at 45 kph. If Car A rests for one hour on the way, in how many hours after they left will they meet?

50(t-1) + 45 t = 330
95 t - 50 = 330
95 t = 380
t = 380/95 about 3 hours
380/95 is exactly 4 hours.
