plsssssssssssss HELP WITH THIS MATH PROBLEM!!!!!!!!!!!!!!?
For the annual breakwater sailboat race, sailboats start singly at 1 minute intervals. Boat B is scheduled to start immediately following boat A. The captain of boat B feels that no matter how fast boat A travels his boat can sail 1 km/hr faster. What is the average speed of each boat if Boat B overtakes Boat A at the 1st buoy, 4 Km from the start?
I wll choose a best answer. Can you guys please show me how to do the steps for this word problem as I really need to understand it!!!
Thanks once agan 
d = rt
let speed of slower boat be x km/hr , then
4 = xt = (x+1)(t – 1/60)
xt = xt -x/60 + t -1/60
t = (x+1)/60
xt = 4 = x(x+1)/60
x(x+1) = 240
solve to get
———————-
x = 15 km/hr
x+1 = 16 km/hr
