Question

the temperature during the day is 5.4°c. after sunset, the temperature falls 7.5°c. wind - chill makes the temperature after sunset feel 6.3°c colder. what temperature does it feel like after sunset? show your work.

Explanation:

Step1: Find the temperature after sunset without considering wind - chill

The temperature during the day is $5.4^{\circ}C$ and it falls $7.5^{\circ}C$ after sunset. So the temperature after sunset without wind - chill is $5.4 - 7.5=- 2.1^{\circ}C$.

Step2: Consider the effect of wind - chill

The wind - chill makes it feel $6.3^{\circ}C$ colder. So the felt - like temperature is $-2.1-6.3=-8.4^{\circ}C$.

Answer:

$-8.4^{\circ}C$
