Let the train will meet ‘t’ hours after the train from station Q started Distance travelled by train started from station P = 84 x 40/60 km Distance travelled by train started from station Q = (84 + 100) x t km Total distance between station P and Q = 792 km Now, 84 x (40/60) + (84 + 100) x t = 792 ⇒ 56 + 184t = 792 ⇒ 184t = 792 – 56 = 736 ⇒ t = 736/184 = 4 hours Distance travelled by train starting from station P at all meeting point = 56 + 84 x 4 = 392 km
