Answer:
59/ 60
Step-by-step explanation:
1.9 can be expressed as 19/10
Thus, our equation becomes
19/10 -11/12.
This becomes (228 -110) / 120
= 118 / 120
Simplify by 2 to get
59/60
A) The differential equation comes from the fact that the rate of temperature change is proportional to the difference in temperatures.

B) Find general solution by separating variables and integrating

:
C) Initial condition is t=0, T = 87

D) Total time elapsed is 10 minutes, new temperature is 84

solve for alpha

E) Temperature function is:

solving for t

Plug in T = 98.6

This is approximately 32 minutes before he arrived or about 1:20 AM
