Chapter 9.6, Problem 26E

To determine

To find the distance of that the sailor can see in miles.

Answer to Problem 26E

The distance of that the sailor can see in miles = $2.miles$

Explanation of Solution

Given: Height $=3\text{ ft}$

Calculation:

  $\begin{array}{l}h=\frac{d^2}{1.4}\\ \Rightarrow d^2=h\ast 1.4\\ \Rightarrow d=\sqrt{h\ast 1.4}\\ Given\text{ that, h=3 ft}\\ \Rightarrow d=\sqrt{3\ast 1.4}=2.05\approx 2miles\end{array}$

Hence, the distance of that the sailor can see in miles= $2.miles$
