Question 776781: A train leaves Philadelphia at 5:00 P.M. A second train leaves the same city in the same direction at 8:00 P.M. The second train travels 75mph faster that the first. If the second train overtakes the first at 10:00 P.M., what is the speed of the two trains. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A train leaves Philadelphia at 5:00 P.M. A second train leaves the same city in the same direction at 8:00 P.M. The second train travels 75mph faster that the first. If the second train overtakes the first at 10:00 P.M., what is the speed of the two trains.
-------
2nd train DATA:
time = 2 hrs ; rate = x + 75 mph ; distance = 2(x+75) = 2x+150 miles
------
1st train DATA:
time = 5 hrs ; rate ; x mph ; distance = 5x miles
------------------
Equation:
distance = distance
5x = 2x+150
3x = 150
x = 50 mph (speed of the 1st train)
x+75 = 125 mph (speed of the 2nd train)
