The dis between two stationsA and B is 540 km. Two trains start simultaneously from these stations on parallel tracks to cross each other. The speed of one of them is greater than the other by 5 km per hour. If the distance between these two trains after 3hours of their start is 165 km find the speed of each train?

let the speed of one train is x km/h
then the speed of another train is (x+5)km/h
distance travelled by first train in three hour is x*3=3x
distance travelled by another train is(3(x+5)=3x+15
the total distance travelled by two trains are 3x+3x+15=6x+15
acc.to.ques.
6x+15=540
6x=540-15=525
x=525/6=175/2 km/h
speed of another train=175/2+5=185/2 =92.5 km/h
then the speed of another train is (x+5)km/h
distance travelled by first train in three hour is x*3=3x
distance travelled by another train is(3(x+5)=3x+15
the total distance travelled by two trains are 3x+3x+15=6x+15
