A to B, and B to A, two different trains, meet in the middle, different departure times. The wording is a little oddly organized, but the total distance traveled will be the distance between A and B, which is 215 miles. This is given in the last sentence of the description.
___________speed_____________time_________distance
A to B______50________________t+1
B to A______60_________________t
Total_______________________________________215
Find the distance expressions using rate*time=distance.
___________speed_____________time_________distance
A to B______50________________t+1___________50(t+1)
B to A______60_________________t____________60t
Total_______________________________________215
Total distances make for the equation to solve for t,
