Q1. Two trains are moving in opposite directions 60 km/hr and 90 km/hr. Their lengths are 1.10 km and 0.9 km respectively. The time taken by the slower train to cross the faster train in seconds is_________?
Answer: 48
Explanation: Relative speed = 150 km/h = 125/3 m/s; total length = 2000 m; time = 2000 ÷ (125/3) = 48 seconds.
