Question

The distance d (in miles) that you can see to the horizon with your eye level h feet above the water is given by d=3h2−−−√. You are standing on a platform. Your eye level is 12 feet above the water. Can you see a ship that is 4.5 miles away? because you can see about miles.

Answer 1

Answer: He cannot see a ship that is 4.5 miles away.

Step-by-step explanation:

Since we have given that

$d=3\sqrt{h}$

Here, h is the eye level above the water

d is the distance away.

If h = 12 feet

We will get :

$d=3\sqrt{12}\\\\d=3\times 2\sqrt{3}\\\\d=6\sqrt{3}\\\\d=10.39$

Hence, it is 10.39 feet away when eye level is 12 feet above the water.

Therefore , he cannot see a ship that is 4.5 miles away.
