Two trains 132m and 108m in length are running towards each other on parallel lines at the rate of 32km/hr and another at 40km/hr.In what time will they be closer to each other from the moment they meet?
Relative speed=32+40=72km/hr=72*(5/18)=20m/s
Total length=132+108=240m
Time=Length/speed=240/20=12
A train 150m long passes a telegraph post in 12s.Find speed of the train.
A train is running at the rate of 40km/h. A man is also going in the same direction parallel to the train at a speed of 25km/hr. If the train crosses the man in 48s find length of the train.
How many seconds will a train 60m in length, travelling at the rate of 42km/hr take to pass another train 84m long, proceeding in the same direction at the rate of 30km/hr.
Length of two trains running in opposite directions are 170m and 190m repectively.If Speed of the first is 30km/hr and the second is 24km/hr,find in how many seconds will they meet?
Two trains are moving in the same direction at 50km/hr and 30km/hr.The faster train crosses a man in the slower train in 18s.Find length of the faster train.
