275 beacues if u and 50 five times it would of been 250 but u an the five two the 50 and u and 55 five times and u get 275
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.
THE ANSWER IS LYFE 3432423
One number is 18 and the other is 22
D, think as 13 dividing 2, you get 6 and have one left
