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.
