Question 470271: A boy traveling by a canoe can go downstream 6 miles per hour and upstream 2 miles per hour. How fast can he go in still water, and what is the rate of the current?
Answer by Gogonati(855) (Show Source): You can put this solution on YOUR website!
Let the rate of the current be x miles per hour.The speed of the canoe downstream will be: 6-x, and upstream 2+x.Since the rate of the current does not change we write: 6-x=2+x, solving this equation we get x=2 miles per hour, is the rate of change of the current.
Answer:On still water the canoe travel 6-2=4 or 2+2=4 miles per hour, and the rate of the current is 2 miles/h.
