Question

Kashish goes 30 meters north then turns right and walks 40 m, then again turns right and walks 20m then again turns right and walks 40m how many meters is he from his original position

Answer 1

See the attachment.

First goes 30m north(blue line)

Then turn right and go 40m(upper red line)

Then turn right and go 20m(yellow line)

Then turn right and go 40m(lower red line)

Finally, distance from starting point = 30 - 20 = 10m

Answer: 10m

Answer 2

10m
OB=30
OB=OA+AB
30=OA+20
30-20=OA
OA=10M
So, he is 10m from his original position.
