Answer
Cindy must travel a distance of 4.92 miles at an angle of $24.0^{\circ}$ north of east.
Work Step by Step
The east component of Cindy's displacement is 1.50 mi + 3.00 mi = 4.50 mi east.
The north component of Cindy's displacement is 2.00 mi north.
We can find the distance Cindy must travel:
$\sqrt{(4.50~mi)^2+(2.00~mi)^2} = 4.92~mi$
We can find the direction north of east:
$tan~\theta = \frac{2.00~mi}{4.50~mi}$
$\theta = tan^{-1}(\frac{2.00~mi}{4.50~mi})$
$\theta = 24.0^{\circ}$
