A car travels 700m North and then 300m East and then 300m South. This journey takes 1 min and 40s. The total displacement is m
and the average velocity is
m/s

Step-by-step explanation:

North=700m

East= 300m

South=300m

y=700-300=400m

x= 300m

We know that the displacement is found using the Pythagoras theorem

let the displacement be d

d^2= x^2+y^2

d^2= 400^2+300^2

d^2= 160000+90000

d^2=250000

d=√250000

d=500m
