Question

In January 2008, the temperature in parts of Minnesota fell from 48∘
F to -12∘
F over a 24-hour period. What was the average temperature change per hour?

Answer 1

Answer:

Atmospheric ice accretion caused by freezing precipitation (FP) can lead to severe damage and failure of buildings and infrastructure. This study investigates projected changes to extreme ice loads – those used to design infrastructure over North America (NA) – for future periods of specified global mean temperature 

Answer 2

The average change in temperature fall is 1.5° F/hour

Step-by-step explanation:

In January 2008, the temperature in parts of Minnesota fell from 48° F to -12° F over a 24-hour period.

Average temperature per hour $=\dfrac{\text{Change in temperature}}{\text{Change in time}}$

In January 2008

• At time, t = 0

Initial Temperature, Ti = 48° F

• After 24 hours, t = 24

Final temperature, Tf= -12° F

$\text{Average temperature change}=\dfrac{-12-24}{24-0}$

$\text{Average temperature change}=\dfrac{-36}{24}\approx -1.5^\circ F/h$

Hence, the average change in temperature fell down is 1.5° F/hour
