The time it takes the boat to travel miles upstream is / (r - 7) time = distance / rate. Going DOWNSTREAM, the current will move the boat along faster than it . Apr 14, �� 1) If the speed of the boat or swimmer is X km/hr and the speed Speed Of The Boat Going Upstream And Downstream of the stream is Y km/hr, The speed of the boat or swimmer in the direction of the stream is known as speed downstream. It is given by; Speed downstream= (X+Y) km/hr. And, the speed of the boat or swimmer against the stream is known as speed upstream. Downstream speed = b + c. When a boat travels against the current, it travels upstream. In this case, its total speed is. Upstream speed = b ? c. Problem. The speed of a boat in still water is 30 mph. It takes the same time for the boat to travel 5 miles upstream as it does to travel 10 miles downstream. Find the speed of the current.

Hence, speeds are subtracted while going upstream. If you just remember this concept, you won't need to remember and recall the above formula while solving the problems. Halving this would give you the speed of the current. Once you know how to deal with these 4 types of problems, the chapter should be an easy one for you.
