Train Q of length 360m can cross a pole in 12sec and it can cross train P running in opposite direction in 100/7 sec. If the speed of train P is 2/5 of train Q then Find the the length of train P?
Speed of train Q = 360/12 = 30 m/s Speed of train P = 2/5 x 30 = 12 m/s Accordingly, (l + 360)/(12 + 30)= 100/7 there for the length of the train P will be length of train p =240 m Ans.
