Question 263482: The speed of a boat in still water is S ft/sec. The current is moving at a rate of C ft/sec. Write an expression to represent the boat�s speed going upstream.

S = speed of the boat in calm water
C = current of a river flowing downstream
R = rate of the boat going upstream against the current,
so the current 'C' must be subtracted from the boar's speed 'S'
R = S - C
