David is rowing a boat Upstream the river is Flowing at a speed of 2 miles per hour David starts rowing a speed of 6 miles per hour but as he gets tired his speed decreases at a rate of 1 miles per hour every hour. which equation represents a speed of the boat for X hours spent rowing
David's rowing speed is
\(6-x\)
but since he is rowing against a current of 2 mph, the equation becomes
\((6-x)-2=4-x\)
