Question 894228
If a person's eye level is "h" meters above sea level and he can see "d" kilometers to the horizon, then "d"=3.57sqrt"h"
{{{d = 3.57sqrt(h)}}}.
 Suppose the person's eye level is 11.56 meters above sea level.
 How far can he see to the horizon? Round your answer to the nearest tenth. 
{{{d = 3.57sqrt(11.56)}}}
d = 3.57*3.4
d = 12.1 km
