Two trains are moving in opposite directions at speeds of 60 km/h and 90 km/h. 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
Explanation:
Relative speed of both trains = 60 + 90 = 150 km/hr
Total distance = 1.10 + 0.9 = 2 km
∴ Required time = (2 × 60 × 60)/150 = 48 seconds
Hence, option (d).
