Question
The distance between stations X and Y is 672 km. A train
leaves X at 9 a.m. at 64 km/h. Another train leaves Y at 10:30 a.m. towards X at 96 km/h. When will they meet?Solution
Time gap = 1.5 hrs → Distance = 64 × 1.5 = 96 km
Remaining = 672 – 96 = 576 km
Relative speed = 160 km/h
Time = 576 / 160 = 3.6 hrs = 3h 36m
Meeting time = 10:30 a.m. + 3h 36m = 2:06 p.m.
