Two trains A and B are running at 40 kph and 20 kph respectively. If the faster train completely passes a man sitting in the slower train in 5 seconds then what is the length of the faster train.
Train A and B are running in opposite direction and approaching a station. If they cross a man standing on the platform in 27 sec and 17 sec respectively and they cross each other in 23 sec. Find the ratio of their speeds.
Let ratio of their speed be x:y
Length of A = 27x
Length of B = 17y
so, (27x + 17y) / (x + y) = 23
or, x/y = 3/2
Two trains, each 100m long are running in opposite direction. If it takes 8 seconds for them to cross each other and one train is moving twice as fast as the other. Then, what is the speed of the faster train.
There are two trains A and B running between city X and Y. Train A starts from city X to city Y and train B starts from city Y to X. After they meet, they reach their destinations after 9 hours and 16 hours respectively. Find the ratio of their speed.
Find the time taken by a 100 m long train running at 144 kph to cross an electric pole.
Have fun learning :-)
