Two trains with a speed of 80 km/h and 120 km/h, respectively, are 500 km apart and face each other. Find the distance between them 10 minutes before crossing.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 33.33km
Formula used
Meeting time = Distance/relative speed
Calculation
10/60 = Distance/(120 + 80)
Hence, the distance between them 10 minute before crossing = (120 + 80) × 10/60 = 33.33km
