<u>Solution: </u>
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 =
So, the average temperature dropping is 4.14 degrees per hour.
