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)
----------
