A train leaves Station P at 5:00 AM and travels towards Station Q at a speed of 50 km/h. Another train leaves Station Q at 7:00 AM and travels towards Station P at a speed of 100 km/h. The distance between the stations is 600 km. At what time will the two trains meet?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 10:20 AM.
Distance covered by train from P in 2 hours = 50 × 2 = 100 km
Remaining distance between trains when second train starts = 600 - 100 = 500 km
Combined speed = 50 + 100 = 150 km/h
Time taken to meet after second train starts = 500/150 = 10/3 hours = 3 hours 20 minutes
Meeting time = 7:00 AM + 3 hours 20 minutes = 10:20 AM
