Two Trains Are Moving In Opposite Directions At 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» Relative speed = 60 + 90 = 150 km/hr. = 150 * 5/18 = 125/3 m/sec. Distance COVERED = 1.10 + 0.9 = 2 km = 2000 m. Required TIME = 2000 * 3/125 = 48 sec. Relative speed = 60 + 90 = 150 km/hr. = 150 * 5/18 = 125/3 m/sec. Distance covered = 1.10 + 0.9 = 2 km = 2000 m. Required time = 2000 * 3/125 = 48 sec. |
