Answer:

total distance = 3300 ft

Step-by-step explanation:

we know here displacement S is in vector form that is

$\vec{S} = \vec{S1} +\vec{S2}+\vec{S3}+\vec{S4}$ ......................1

$\vec{S} = (3\hat{i}+6\hat{j}) + (-7\hat{i}-3\hat{j})$

and

$\vec{S} =(-4\hat{i}+3\hat{j})$

and

magnitude is

$\left| \vec{S} \right| = \sqrt{(-4)^2+3^2}$

$\left| \vec{S} \right| = \sqrt{25}$

$\left| \vec{S} \right| = 5$

so here distance from home to cafe is

S = 5 × 660

total distance = 3300 ft
