The captain of a fishing boat needs to travel 22 miles  on his boat. If the captain goes the same direction the current is flowing, his trip would be 4 hours long, but it would be 5 hours long if he goes the opposite direction of the current.  Let  x represent the rate of the boat if there were no current, and let y represent the rate of the curre nt. Recalling that distance equals rate multiplied by time, what is an equation  that describes the situation when the boat is traveling the same direction as the current is flowing.
