Let the speed of the goods train be ‘s’ km/hr Distance covered by goods train in 17 hrs = s x 17 km Distance covered by express train in 7 hrs = 7 x 204 km Distance covered by goods train in 17 hrs = Distance covered by express train in 7 hrs So, 17s = 7 × 204 ⇒ 17s = 1428 ⇒ s = 1428/17 = 84 So, Speed of goods train = 84 km/hr
