Question 92679: I just got the answer to a problem I asked earlier ... thank you. Now, I have another question that is similar and I want to see if I am understanding this correctly.
Two trains left a station at the same time. One traveled north at a certain speed and the other traveled south at twice the speed. After 4 hours, the trains were 600 miles apart. How fast was each train traveling?
This is what I came up with ... am I right?
d = 400
t = 4
r = x (1st train) and 2x (2nd train)
400 = 4(x)+4(2x)
400 = 4x + 8x
400 = 12x
x = 33.33
2x = 66.66 Answer by stanbon(75887) (Show Source):
