A boy travelled towards north 8 km from
point A, as shown in the figure, then he
took a turn to east and travelled further 3
km and again he took a turn to south
reached 'B' by travelling 5 km. The
displacement of the from A to B journey is
km.

Answer 1

Answer:

For this we need to use the pythodoras theorem .

Since the boy travels south by 5 km , lets take AB = 3

the distance traveled east will be the value of BC ie BC = 3

AC² = AB² + BC²

       = 3² + 3²

       = 9 + 9

       = 18

AC = √18

     = 3√2 km
