Answer:

4) a)
$s = +4\,mi$ , b)
$\Delta s = 2\,mi$ , 5) a)
$s = -2\,mi$ , b)
$\Delta s = 10\,mi$

Step-by-step explanation:

4) Let assume that distance with respect to origin is positive at east, while distance is negative at west.

a) The initial displacement is:

$s = +4\,mi$

b) The distance travelled is:

$\Delta s = 2\,mi$

5) a) The final displacement is:

$s = -2\,mi$

b) The total distance travelled is:

$\Delta s = 2\,mi + 6\,mi + 2\,mi$

$\Delta s = 10\,mi$
