Question

Minnesota fell from 48 degrees to -12 degrees over a 24 hour period. what was the average temperature change per hour?

Answer 1

We have to calculate the average temperature change per hour.

We know that the temperature drops from 48 degrees to -12 degrees in 24 hours.

To calculate the average change, in degrees per hour, we calculate the ratio between the variation of the temperature and the interval of time.

We can expres this as:

`v=(\Delta T)/(t)=(T_f-T_i)/(t)=(-12-48)/(24)=(-60)/(24)=-2.5`

Answer: The average change in temperature is -2.5 degrees per hour.
