a student walks 3 miles west and then 4 miles south to get to school the student displacement was

draw an x y axis

3 miles west is 3 miles to the left, -3
4 miles south is 4 miles down, -4

connect the the point to the origin, that side is what you are looking for
that side is also hypotenus

using Pythagorean theorem

sqrt(-4^2 + 3^2)
sqrt(25)
5

your displacement is 5

We have that a student walks 3 miles west and then 4 miles south to get to school the student displacement was

D=7miles

From the question we are told

a student walks 3 miles west and then 4 miles south to get to school the student displacement was

Generally the equation for the displacement is mathematically given as

D=intial travel +final Travel

Therefore

D=3+4

D=7miles

Therefore
