Boats and Streams

The speed of a boat along the stream is $12$ $\mathrm{kmph}$and against the stream is$6$ $\mathrm{kmph}$. What is the speed of the boat in still water (in $\mathrm{kmph}$)?

The speed of a boat in still water is $20$ $\mathrm{kmph}$and the rate of flow of the river is $4$$\mathrm{kmph}$. Moving along with the stream, a boat went $120$ $\mathrm{km}$. What distance will the boat cover in half the previous time going against the stream?

At his usual rowing rate, Anil can travel $6 \mathrm{km}$ downstream in a certain stream in $3$ hours less time than it takes him to travel the same distance upstream. If he doubles his rowing rate, then he would take only $\frac{1}{2}$ hour more for the upstream $6 \mathrm{km}$ than for the downstream $6 \mathrm{km}$. What is the speed of the stream?

If a boat goes $12 \mathrm{km}$ km along the stream in an hour and $5 \mathrm{km}$ km against the stream in the same time, then find the speed of the boat in still water.

Sita can swim $9$ $\mathrm{km}$upstream and $20$ $\mathrm{km}$downstream in $8$ Hours. Also, she can swim $12$ $\mathrm{km}$upstream and $8$ $\mathrm{km}$ downstream in $6$ Hours. Find the downstream speed.

Ram can swim at the speed of $6$ $\mathrm{kmph}$in still water. If the speed of the current is $2.4$ $\mathrm{kmph}$, it takes $3 \mathrm{h} 20$ $\min$to cover the distance from A to B and B to A. Find the distance between points A and B.

Swimita can row $12$ $\mathrm{kmph}$in still water. It takes her five times as long to row up as to row down the river. Find the speed of current.Enable GingerCannot connect to Ginger Check your internet connection

Raman takes $2 \mathrm{h} 30$ $\min$to row a boat $12$ $\mathrm{km}$downstream of a river and $1 \mathrm{h} 45$ $\min$to cover a distance of $6$ $\mathrm{km}$ upstream. Find the speed of the river current.

In a stream running at $5 \mathrm{kmph}$, a man goes $10 \mathrm{km}$ upstream and comes back to the starting point in $50$ minutes. Find the speed of the man in still water.

A boat covers a distance of $20 \mathrm{km}$ Upstream in $5$ hours, and it covers a distance of $60 \mathrm{km}$ Downstream in $6$ hours. Find the speed of the boat in still water?
