Question

a train leaves jaipur to delhi at 3:45 p.m. and goes at the rate of 50 per hour and another train leaves delhi for jaipur at 2:35 a.m. and goes at the rate of 60 km per hour if the distance between both is 6:20 at what distance from jaipur will the two trains meet

Answer 1

Answer:

Distance between Jaipur and Delhi - 720 km

When the train from Jaipur to Delhi will start ,Train from Delhi to Jaipur will cover = 60*70/60(ahead start of 70 min) = 70 km

Distance left = 720 -70= 550 km

Relative speed = 50+60 =110 km

Time taken to meet = 550/110 = 5 hrs

So distance covered by train from Jaipur in 5 hrs = 50×5= 250km. ans
