$\mathfrak{\green{ANSWER:}}$

✔Downstream/Upstream:

✔In water, the direction along the stream is called downstream. And, the direction against the stream is called upstream.

✔If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then:

✔Speed downstream = (u + v) km/hr.

✔Speed upstream = (u - v) km/hr.

✔If the speed downstream is a km/hr and the speed upstream is b km/hr, then:

✔Speed in still water =1/2(a + b) km/hr

✔Rate of stream =1/2(a - b) km/hr

Answer 2

hey guys

here is your answer. .....

• Downstream/Upstream:

• In water, the direction along the stream is called downstream. And, the direction against the stream is called upstream.

• If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then:

• Speed downstream = (u + v) km/hr.

• Speed upstream = (u - v) km/hr.

• If the speed downstream is a km/hr and the speed upstream is b km/hr, then:

• Speed in still water =1/2(a + b) km/hr

• Rate of stream =1/2(a - b) km/hr
