Question 1050312: two train starts simultaneously from two stations 500 km apart and move toward each other the speed of one train is more than the other by 20 km/hr if the distance between the two trains after 6 hours is 20 km find the speed of two trains? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! two trains start simultaneously from two stations 500 km apart and move toward each other the speed of one train is more than the other by 20 km/hr if the distance between the two trains after 6 hours is 20 km find the speed of two trains?
------
1st train DATA:
rate = x km/hr ; time = 6 hrs ; distance = 6x km
-------
2nd train DATA:
rate = x+20 km/hr ; time = 6 hrs ; distance = 6x+120 km
-----------------------
6x + 6x + 120 = 480 km
12x = 360 km
x = 30 km/hr (1st train rate)
x+20 = 50 km/hr (2nd train rate)
