Question 1042401: Black ice is an ice covering on roads that is especially difficult to see. It is therefore extremely dangerous for drivers. If a car travelling 30 mph brakes suddenly on black ice, it will slide across the ice. The distance D (in feet) that the car will slide is related to the temperature T (in degrees Celsius). For example, the car will slide a distance of 168 feet when the temperature is -3 degrees Celsius, and the sliding distance increases 4 feet for every 1 degree decrease in temperature. Write a linear equation for the sliding distance D in terms of the temperature T. Answer by robertb(5830) (Show Source):
