The formula for relating the distance to the horizon and your height is d = 1.5h, where d is the distance to the horizon in miles, and h is your height in feet. Round your answers to the nearest tenth of a mile or foot. a) You are standing on the observation deck of a skyscraper, which is 1350 feet above the ground. It's a clear day, and you can see for miles and miles. Your daughter asks you just how far it is to the horizon. You answer: "It is , to the nearest tenth of a mile." b) Suppose now you are in a lifeboat standing up looking for a passing ship. How far is it to the horizon? Suppose you are 5.9 feet tall.
