Chapter 12.7, Problem 39CCR

To determine

To find : How far did the elevator travel

Answer to Problem 39CCR

  $24.6$ miles

Explanation of Solution

Given information :

  

The given information is, as point A in north direction and point C 11 miles away from point B.

Formula Used:

  $A{C}^2=A{B}^2+B{C}^2$ [By Pythagoras Theorem ]

Calculation :

Distance from starting to last point is AC.

So, ${(AC)}^2={(22)}^2+{(11)}^2$

  $\begin{array}{l}$ {(AC)}^2=484+121$$ {(AC)}^2=605$AC=\sqrt{605}=24.6\text{ miles}\end{array}$
