A boat can travel km upstream and 25 km ...

A boat can travel km upstream and 25 km downstream in the same time. Find how many times the speed of the boat in still water it to the speed of the stream .
The following steps are involved in solving the above problem . Arrange them in sequential order.
(A) Let the speed of the boat in still water by x kmph and speed of the stream by y kmph
(B) `(25)/(x + y) = (15)/( x - y)`
(C) Speed of the boat downstream = (x + y) kmph and the speed of the boat upstream = (x - y) kmph
(D) Speed of the boat in still water is 4 times the speed of the stream.
(E) x = 4 y
