By noon the temperature was 17^o lower than the start of the day. If the temperature was -5^o F at noon, what was the temperature at the start of the day?

At 9 AM the temperature was -4^o C. By noon the same day, the temperature was 2^o C. How many degrees did the temperature change during the 3 hours?

Wind chill describes how cold it feels. When the temperature is 2^o C, a 20 mph wind can make it feel like it is -4^o C. What is the difference between the actual temperature and the wind chill factor for the situation described above?
