Recall your d = rt, distance = rate * time
so... one train goes west and the goes the opposite way... alrite... so... notice, by the time 338 miles have been covered by both, it will have been "t" hours, and whatever "t" is, is the same amount of time the westbound train has been running as well as the eastbound train has been running.
now, let's say, since by "t" hours they've covered 338 altogether, so, if the westbound train has covered say "d" miles, then the eastbound train would have covered the slack from 338 and d, that is, "338 - d".
so, 2hours and 36 minutes.

Answer:
is the probability that a player draws out two tiles of the same color assuming they are drawing one tile from each bag.
Step-by-step explanation:
In each bag there are red, green, and blue tiles, meaning that no matter which color is pulled out first there is always some probability that the second tile will be the same color. So, we can set up three possible outcomes:
Red: The player pulls out a red tile first. This has a probability of happening. Then in order to succeed for the problem, the next tile also needs to be red which has a
probability attached to it.
×
=
probability of happening.
Green: There is a probability of the player pulling out a green tile first. In this case we want to calculate the probability of the second tile being green, which would be
.

=
.
Blue: There is a probability of the first tile being blue in which case we are hoping for the second tile to be blue as well. The probability of the second tile being blue is
on its own, and them both being blue is
×
=
Adding +
+
we get the answer
