Train A crosses a man running in opposite direction in 16 seconds. Speed of man is 18 km/hr. and speed of train A is 72 km/hr. Find length of train A (in meters)?
Train A crosses a platform of 98 m length in 24 sec. Another Train B of same length as Train A crosses a pole in 12 sec. If speed of train A is 20% more than speed of train B. Find length of train A.
The ratio of length of train A to B is 5 : 4 and speed of train A is 90 km/hr. If train A crosses a pole in 12 seconds and train A crosses train B in 36 seconds while running in same direction, then find time taken by train B to cross a 400 meters long platform.
Note: Answer check: the data allows two answers, depending on whether train B is faster or slower than A; the source key picks one.
