Answer (as printed):
Explanation
Let the original speed of the train be x km/hr. 360 360 600 360 240 Then, – =4⇔ – =4⇔ = 4 ⇔ x = 60. 3 x x x x x 5 Let the total distance travelled by the train be y km. 150 ( y – 150) y 5 ( y – 150) y Then, + – =8⇔ + – = 8 ⇔ 2x = 1740 ⇔ x = 870. 60 3 60 2 36 60 × 60 5 Hence, required distance = 870 km. 1 1
