Question 18
A stream which flows from west to east in the middle turns left. Further, then it comes across an island and goes around it in an anti-clock manner to take a quarter circle of the island, Then it takes a right from that direction.
Determine that finally in which direction is the stream flowing ?
Solution
A stream is flowing from west to east and it takes a left turn in the middle. So, now the stream is facing North.
Now, it comes across an island and covers a quarter circle of the island in the counter clockwise direction.
The above diagram shows the way the stream is moving.
Hence, after taking a right turn from the island, the stream is again facing East.
