What was the temperature at the end of the 4 hours?
Understand the Problem
The question is asking for the final temperature after a series of changes over four hours, starting from an initial temperature of 62 °F. We need to calculate the total change and apply it to the initial temperature.
Answer
The final temperature is $64 \text{ °F}$.
Answer for screen readers
The final temperature at the end of the four hours is 64 °F.
Steps to Solve
-
Identify Initial Temperature The initial temperature is given as 62 °F.
-
Calculate Total Change in Temperature Add the changes in temperature over the four hours:
- Hour 1: +2 °F
- Hour 2: +3 °F
- Hour 3: -2 °F
- Hour 4: -1 °F
Total change: $$ \text{Total Change} = 2 + 3 - 2 - 1 = 2 \text{ °F} $$
- Calculate Final Temperature Add the total change to the initial temperature: $$ \text{Final Temperature} = \text{Initial Temperature} + \text{Total Change} = 62 \text{ °F} + 2 \text{ °F} = 64 \text{ °F} $$
The final temperature at the end of the four hours is 64 °F.
More Information
The changes in temperature reflect fluctuations that can commonly occur in different environments. In this case, after a series of increases and decreases, it results in a slight net increase from the original temperature.
Tips
- Forgetting to include negatives: Always pay attention to signs for temperature changes.
- Incorrectly summing changes: Ensure accurate addition and subtraction for each hour's change.
