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.
