Question 883499: A fishing boat made a trip to St. Vincent and back. On the trip there it traveled 8 mph and on the return trip it went 28 mph. How long did the trip there take if the return trip took four hours. How do you do this problem ?

You can put this solution on YOUR website! RT=D basic uniform rates travel fact.
R = rate
T = time
D = distance
Data table helps to sort the different described data in the problem.
__________________speed___________time___________distance
GOING______________8______________(___)__________(_______)
RETURNING__________28______________4_____________(_______)
The question, "how long did the trip there take", is for the "GOING" part of the trip. This is the main variable that you want to solve. The distance in both directions is the same each way (assumed). That gives you a way to relate the GOING and the RETURNING. You can set-up two equations and these two equations have a variable for the distance, which can be eliminated using a substitution.
That all should be enough for you to continue analyzing and solve the problem the rest of the way.
.... One more big hint:
__________________speed___________time___________distance
GOING______________8______________(___)____________d
RETURNING__________28______________4_______________d
