Let the speed of the goods train be ‘s’ km/hr Distance covered by goods train in 18 hrs = s x 18 km Distance covered by express train in 7 hrs = 7 x 144 km Distance covered by goods train in 18 hrs = Distance covered by express train in 7 hrs So, 18s = 7 × 144 ⇒ 18s = 1008 ⇒ s = 1008/18 = 56 So, Speed of goods train = 56 km/hr
