A train covers the distance between two stations X and Y in 6 hours. If the speed of the train is reduced by 13 km/h, then it travels the same distance in 9 hours. Find the distance between the two stations
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 234 km
Concept used:
when the distance is constant, speed is inversely proportional to the time
Calculations:
Ratio between the usual time and increased time = 6 : 9
Ratio of speed = 9x : 6x
According to the question;
⇒ 3x - 2x = 13
⇒ x = 13
Speed after increased time = 2 × 13 = 26 km/h
Required distance = time × speed = 9 × 26 = 234 km
