Astudent bikes to school by traveling first dn = 1.00 miles north, then dw = 0.400 miles west, and finally ds = 0.100 miles south.

Here student moves as

North

West

South

Now total distance moved by the student is just the algebraic sum of all

So it is

So here we can also find the displacement

displacement is the straight line distance between initial and final position

so net displacement here towards north direction is given as

North

net displacement towards west is

now the net displacement will be given by Pythagoras Theorem

and direction is given as

North of west
