Question

a person walking on a straight line 60m. then he turns right 90 degree and travel hundred metre. again he turns right 90 degree and travels 60m. find the total distance travelled?. find the total displacement? ​

Answer 1

Answer:

Total displacement is 100 m.

Explanation:

For understanding,

let first traveled distance be AB = 60m.

2nd distance be BC = 100m.

3rd distance be CD = 60 m.

So the displacement is DA.

now angle between AB and BC = BC and CD = 90° - (i)

AB = CD - (ii)

by (i) and (ii) , it shows that it forms a rectangle . In a rectangle opposite sides are equal,

therefore, AB = CD = 60m

BC = DA = 100m
