Question

86. A train travelling at the speed of 50 km/h leaves from a station. Another train
travelling at speed of 60 km/h leaves the same station after 7 h in the same
direction. They will meet after what distance?
(111800 km (2) 2100 km (3) 2400 km (4) 2700 km (5) 2800 km​

Answer 1

Answer:

in 7hours A travel = 50*7 = 350 km

now usual speed of both in same direction = (60-50) = 10km/h

Time to meet = D/S = 350/10 = 35 hours .

so, in 35 hours A travel = 35*50 = 1750km.

Total distance covered by A = 1750+350 = 2100km(B) (Ans)
