Answer:

Step-by-step explanation:

If we ASSUME that the temperature drop is linear. (it's probably not)

we get an AVERAGE rate.

- 54 / 22.5 = -2.4°/minute

  • Change in temperature=54°F
  • Time taken=22-1/2 min=22.5min

Now

Per min change

[tex]\\ \sf\longmapsto \dfrac{\Delta T}{\Delta t}[/tex]

[tex]\\ \sf\longmapsto \dfrac{54}{22.5}[/tex]

[tex]\\ \sf\longmapsto 2.4°F/min[/tex]
