Question
A goods train leaves a station at a certain time and at
a fixed speed. After 9 hours, an express train leaves the same station and moves in the same direction at a uniform speed of 176 km/hr, this train catches up the goods train in 7 hours. Find the speed of the goods train.Solution
Let the speed of the goods train be ‘s’ km/hr Distance covered by goods train in 16 hrs = s x 16 km Distance covered by express train in 7 hrs = 7 x 176 km Distance covered by goods train in 16 hrs = Distance covered by express train in 7 hrs So, 16s = 7 × 176 ⇒ 16s = 1232 ⇒ s = 1232/16 = 77 So, Speed of goods train = 77 km/hr
