Two trains start from Delhi and Poona towards each other at 7 a.m. with speeds of 85 km/h and 67km/h, respectively. If they cross each other at 3.30 p.m., the distance between the stations is:
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 1292 km.
We know that
Relative Speed = Total distance/Time
Now, According to the question,
Trains are moving in opposite directions,
Relative Speed = 85 + 67 = 152 km/h
Total time taken to cross each other = 8.5 hours
The total distance between station = Relative Speed × Time Taken
⇒ 152 × 8.5 = 1292 km
Therefore, the distance between the stations is 1292 km
