Q. A boat can travel $15 km$ upstream and $25 km$ downstream in the same time. Find how many times the speed of the boat in still water is 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 be $x kmph$ and speed of the stream be $y kmph$. (B) $\frac{25}{x+y}=\frac{15}{x-y}$ (C) Speed of the boat downstream $=(x+\gamma) kmph$ 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) $x=4 \gamma$

Time and Distance

Solution:

$( A ),( C ),( B ),( E )$ and $( D )$ is the required sequential order.
