In the mid-nineteenth century, explorers used the boiling point of water to estimate altitude. The boiling temperature of water T (in °F) can be approximated by the model T=−1.83a+212, where a is the altitude in thousands of feet. (a) Determine the temperature at which water boils at an altitude of 5000ft. Round your answer to the nearest hundredth. (b) Two campers hiking in Colorado boil water for tea. If the water boils at 191°F, approximate the altitude of the campers. Give the result to the nearest hundred feet.
