1. The temperature was 45°F at 9:30 am and 65°F at 4:20 PM. The temperature decreased by about 3°F per hour until sunset at 6:20 PM. How much warmer was the temperature at 6:20 PM than it was at 9:37 AM? Show your strategy and your work.

2. The temperature was 45°F at 9:30 am and 65°F at 4:20 PM. The temperature decreased by about 3°F per hour until sunset at 6:20 PM. How much warmer was the temperature at 6:20 PM than it was at 9:37 AM? Show your strategy and your work. Notice that there is an extra category – we added temperature!! Step 1: First, we need to know what the temperature was at 6:20 PM. So, we draw a t-chart to figure out the temperature! We know that at 4:20, the temperature was 65°F, and that the temperature decreased by 3°F each hour. Temperature Time Hours and Minutes Temperature 4: 20 ---------------------- 65°F 5:20 + 1 hour- 3°F 6:20 + 1 hour- 3°F 59°F 6:20 2 hours passed 59°F

3. The question is asking how much warmer it was at 6:20 than at 4:20. To answer, we need to check the temperatures at that time and find how much warmer it was at 6:20 than at 4:20. The temperature was 45°F at 9:30 am and 65°F at 4:20 PM. The temperature decreased by about 3°F per hour until sunset at 6:20 PM. the temperature at 6:20 PM How much warmer was the temperature at 6:20 PM than it was at 9:37 AM? Show your strategy and your work. Step 2: Next, we need to read the question again to make sure we are answering it correctly. 65°F at 4:20 We know that it was 65°F at 4:20 at 6:20, the temperature was 59°F. We figured out that at 6:20, the temperature was 59°F. To find how much warmer that is, we subtract! 65°F - 59°F
