Two trains start at the same time from two stations and move towards each other at 20 km/hr and 25 km/hr. When they meet, the faster train has covered 80 km more than the other. What is the distance between the two stations?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 720 km
Both trains run for the same time until they meet, so in every hour the faster train covers \(25-20=5\) km more than the slower one.
Extra distance per hour \(=25-20=5\) km
Time to meet \(\displaystyle =\frac{80}{5}=16\) hr
Distance between the stations \(=(20+25)\times16=45\times16=720\) km
