The correct answer is A
A train running at 90 km/hr crosses a vertical pole in 5 seconds and a platform in 20 seconds. Determine the length of the platform.
Two trains approach each other at 21 kmph and 25 kmph from 2 places 230 km apart. After how many hours they will meet?
A train 270 meter long running with the speed of 80 kmph crosses a bridge in 18 seconds then what is the length of bridge?
Length of a train, whose speed is 108 km/h, is 540 metres. Find the time taken (in seconds) by train to cross a bridge of length 360 metres.
