Avery's temperature dropped 1°F each hour for 3 hours. What is the temperature after 3 hours?

Question

I usually solve this kind of problems with a problem like x-1*3=____ but there is no equals so I would not know who to solve this without Avery's original temperature or ending temperature.

Answer 1

This is a linear problem. Where temperature drops at a constant rate of 1f/ 3 hrs ( Slope)

 

     T =- 1/3 h + R

 

 

     Where R in graph represents the Vertical intercept.

 

     I think that the problem assumes that , temperature drops from normal body temperature which is 98.6F

 

     after 3 hours drops 1 F.
