Given,
The distance Mittu covers towards west = 20m
The distance Mittu covers after a right turn = 40m
The distance Mittu covers after left turn = 20m
To Find,
The direction and distance of Mittu from the starting point.
Solution,
As per the given image,
The distance between initial and final points =
Where are the lengths of hypotenuses of two right-angled triangles.
Length of hypotenuse =
The distance 40m is equally divided, that is 20m each.
∴ =
Similarly,
Thus the total distance =
The direction is northwest as shown in the picture.
Henceforth, Mittu is away and in the northwest direction from the initial point.
