1) A. The temperature changed by 12 degrees from 10F to -2F. B. The temperature changed by 12 degrees in 12 hours so it changed by one degree every hour. 2) Nola hiked faster during the 10 minute walk down an elevation -200 because this is equivalent to -20 every minute, whereas the 20 minute walk down -300 is equivalent to -15 every minute. A steeper incline means a faster speed. 3) The combined temperature of each of my five ice creams is -50 degrees. They each have the same temperature. What is the temperature of one ice cream? 4) Integer A: -6, Integer B: 3. -6/3 = -2. 3/3 = 1. The product of -2 and 1 = -2. -2/1 is also -2. They are equal. This is always true because Integer B is always divided by itself, giving one.
