___________speed________time__________distance
Go_________200__________t+1___________200(t+1)
Back_______250___________t____________250t

Distance expressions come from R%2AT=D, with R rate, T time in hours, D distance in miles.

The distances each way are equal.
200%28t%2B1%29=250t
4%28t%2B1%29=5t
4=t time to get "Back" is 4 hours.
