A girl can row her boat at $5 km/h$ in still water. If she takes $1$ hour more to row the boat $5.2 km$ upstream then to return downstream, find the speed of the stream.
What I had done so far:
Let,
- Velocity of water be $x km/h$
We know,
Velocity of boat is $5 km/h$
Velocity of boat in upstream = $(5-x) km/h$
Velocity of boat in downstream = $(5+x) km/h$
Distance = $5.2 km$
Time taken to cover distance in upstream = $\frac{5.2}{5-x} hours$
Time taken in downstream = $\frac{5.2}{5+x} hours$
Now how can I create a quadratic equation along with this collected observations?
