Question

A body moves 3 m north, then 4 m east and finally 6 m south. calculate the ratio of distance to displacement travelled by the body.

Answer 1

let the body started at A and ended at D. the total distance is 3m + 4m + 6m = 13 m
total displacement is given by the length ED now in triangle AED AD is 4 m ED is 3 M then by Pythagoras theorem it is 5 metres the ratio of distance to displacement is 13 : 5
