Solve each problem. The following letter appeared in the column "Ask Tom Why,"," written by Tom Skilling of the Chicago Tribune: Dear Tom, I cannot remember the formula to calculate the distance to the horizon. I have a stunning view from my 14 th-floor condo, 150 ft above the ground. How far can I see? Ted Fleischaker; Indianapolis, Ind. Skilling's answer was as follows: To find the distance to the horizon in miles, take the square root of the height of your view in feet and multiply that result by 1.224 . Your answer will be the number of miles to the horizon. Assuming that Ted's eyes are \(6 \mathrm{ft}\) above the ground, the total height from the ground is \(150+6=156 \mathrm{ft}\). To the nearest tenth of a mile, how far can he see to the horizon?
