`L_(1)` metre train is moving with a velocity of `v_(1)` m/s and another `L_(2)` m/s in opposite dircetion. Find out (i) The time taken by two train to cross each other (ii) Distance travel by the each train during the crossing.

Answer

(i)`t=(L_(1)+L_(2))/(v_(1)+v_(2))`
(ii)`d_(1)=v_(1)xx((L_(1)+L_(2))/(v_(1)+v_(2)))`,d_(2)=v_(2)xx((L_(1)+L_(2))/(v_(1)+v_(2)))`
