Well she went 3 blocks west....4 north...and then 6 east...so displacement would be

|dw:1398437229944:dw|

Distance between those 2 point = $\large \sqrt{(3)^2 + (4)^2} = \sqrt{25} = 5$ so she is 5 blocks from where she started

The TOTAL distance she traveled would be 3 + 4 + 6 = 13 blocks

Ok but what is the resultant displacement

ok let me thin first

johnweldon1993 · Answer

It would be the 5 I posted before the 13 :)

The displacement would be how far from start you are...well she ends up at that 2nd point...so all you need to do is find the distance from start to finish...which can be done using pythagorea's theorem...which came out to 5
