Question

The temperature in a certain town drops by 1.6℉ per hour for 1.2 hours. It then drops by 0.8℉ per hour for 2.5 hours. Find the total change in temperature.

Answer 1

The total temperature decrease in the town is 3.92℉, calculated by adding the drops over two different time periods with different rates.

Step-by-step explanation:

The total change in temperature in the town can be calculated by finding the temperature decrease in each timeframe and then summing them up. Initially, the temperature drops by 1.6℉ per hour for 1.2 hours, which results in:

• (1.6℉/hour) × (1.2 hours) = 1.92℉

Next, the temperature drops by 0.8℉ per hour for 2.5 hours, which gives us:

• (0.8℉/hour) × (2.5 hours) = 2.00℉

Adding both decreases together:

• 1.92℉ + 2.00℉ = 3.92℉

Therefore, the total change in temperature is a drop of 3.92℉ over the entire period.
