Question

Anju walks 15 meters toward north,then she turns left at 90and walks 30.meters , then turns right at 90° and walks 25 meters .How far is the sh3 from the starting point is in which direction 50 meters north west ,50 metres west,55metres northeast , 60meters north
​

Answer 1

Answer:

Suppose Madhu starts walking from a point A.

She walks 15m towards North, then turns left and walk30m then turns right and walk 25m.

Let D be the end point of Madhu.

Now after completing the walk she make a right angle triangle BCD at point B with base DC=25m and height BC=30m.

∴ BD

=900+625=1525

∴ BD=39m

∴ Madhu is 54m North-West from the starting point.

Hence, option A is correct.
