a 200m long train crosses 400m long bridge with a speed of 36km/hr. calculate time taken by the trai
Asked by | 30 May, 2008, 07:06: PM
Expert Answer

Velocity = 36km/hr = 10m/sec

total distance travelled to cross the bridge = 200m +400m = 600m

speed = distance / time

time = distance / speed

        = 600m /10ms-1

        = 60 sec.
