Question

a boy travels a distance of 10m towards south,then travelled towards east and covered a distance of 20m.calculate total distance and displacement from the initial point​

Answer 1

Answer:

total distance travelled = 10m + 20m =  30m

displacement = 22.5 m

Explanation :

let as consider a triangle ABC

where, AB = 10 m

            BC = 20 m

using pythogoras theorm

AC² = AB² + BC²

AC² = [10]² + [20]²

AC² = 100m² + 400m²

AC² = 500 m²

AC = ²√500 m²

AC = 10√5 m

AC = 10×2.25m

AC = 22.5 m
