A train started from station P and preceded towards station Q at a speed of 90 km/h. 54 minutes later, another train started from station Q and preceded towards station P at 100 km/h. If the distance between the two stations is 651 km, at what distance from station P will the trains meet?
Let the train will meet ‘t’ hours after the train from station Q started Distance travelled by train started from station P = 90 x 54/60 km Distance travelled by train started from station Q = (90 + 100) x t km Total distance between station P and Q = 651 km Now, 90 x (54/60) + (90 + 100) x t = 651 ⇒ 81 + 190t = 651 ⇒ 190t = 651 – 81 = 570 ⇒ t = 570/190 = 3 hours Distance travelled by train starting from station P at all meeting point = 81 + 90 x 3 = 351 km
