Question
Two towns D and E are 576 km apart. A bus starts from D at
5:15 a.m. at 64 km/h. Another bus starts from E at 6:45 a.m. towards D at 80 km/h. When will they meet?Solution
Time gap = 1.5 hrs → Distance = 64 × 1.5 = 96 km
Remaining = 576 – 96 = 480 km
Relative speed = 144 km/h
Time = 480 / 144 = 3.33 hours = 3h 20m
Meeting time = 6:45 a.m. + 3h 20m = 10:05 a.m.
