Question

Adesh walked 200 m to North from his house. Then he turned through 90° and
walked 150 m to West. Again he turned through 90° and walked 300 to North.
After some time, he again turned through 90° and walked 150 m to West. Then he
turned through 90° to his left and walked 100 m to South. How far was he now
from his house?
​

Answer 1

Answer:

Adesh walked 900 m ....

steps= 200+150+300+150+100 = 900

Answer 2

Adesh is 500m far from his home in term of displacement. In term of distance, he is 900m far from his home.

• Total distance = 200+150+300+150+100 = 900m

• From starting point to end point,

                vertical distance between points = 400m

                horizontal distance between points = 300m

                 using Pythagoras theorem,

                 distance from his home = √(〖(vertical distance)〗^2+   〖(horizontal distance)〗^2 )

                                          = 500m
