Question

two trains of equal length are running on parallel lines in same direction at rate of 46km/hr and 36km/hr.The faster train passes slower in 36seconds . The length of each train is

Answer 1

answer :

50 metre.

explanation :

length of each train be = x metres.

distance = x + x = 2x

speed = 46 - 36km/hr

         = 10km/hr

=10 *  ( 5 / 18 ) = 25 / 9m / sec

=2x = 25 / 9 * 36

=2x =900/9

=2x=100

= x = 50

∴ the length of each train is 50m.
