Question

if the ratio of the speed of the upstream and downstream is 3 is to 4 then the ratio of the speed of the boat in still water and speed of the stream is​

Answer 1

Answer:

x-y÷x+y=3÷4

4x-4y=3x+3y

x=7y

x÷y=7y÷y=7÷1

Answer 2

Answer:

let the speed of boat in still water be x

and thr speed of still water be y

so ,x-y/x+y= 3/4

3(x+y) =4(x-y)

3x+3y=4x-4y

x=7y

x/y=7/1

x:y=7:1
