Answer:
A cold front moved in last weekend.The average temperature change for each hour is 4.14 degrees per hour.
Solution:
Given that a cold front moved in last weekend. In 7 hours overnight, the temperate outside dropped 29 degrees
We have to find the average temperature change for each hour.
Average temperature change for 1 hour can be found out by dividing the temperature change for 7 hours (which is 29 degree) by 7 hours.
To compute the average, we need to divide the difference by the time needed, hence we get
Average temperature change for each hour = [tex]\frac{\text {temperature change for } 7 \text { hours }}{7}[/tex]
[tex]\frac{29}{7}=4.14[/tex]
So, the average temperature dropping is 4.14 degrees per hour.
