Final answer:
After calculating the expected temperature drop based on the weather report, it is determined that Daryl should move his plant to a warmer location to ensure that it remains in temperatures above -10°C.
Step-by-step explanation:
The weather report indicates that the temperature is currently 20°C and it is expected to drop by 5°C per hour over the next 6 hours. To determine whether Daryl should move his plant to a warmer location before leaving, we calculate the temperature at the end of the 6-hour period:
- Initial temperature: 20°C
- Temperature drop over 6 hours: 5°C/hour × 6 hours = 30°C
- Expected temperature after 6 hours: 20°C - 30°C = -10°C
Since Daryl wants the plant to remain in temperatures above -10°C and the calculated temperature equals -10°C, it would be prudent for Daryl to move the plant to a warmer location to ensure the plant's safety, accounting for any possible further temperature fluctuations.
