Answer: h = 5
Step-by-step explanation: Starting temp + (change in temp per hour × elapsed hours) = current temp
So...
82+(0.6h)=85
Subtract 82 from both sides to isolate your variable term.
0.6h=3
Divide both sides by 0.6 to solve for hl.
h=5
5 hours have elapsed.
Check your answer. In 5 hours, at 0.6⁰ per hour, the temp would increase by 3 degrees. 82 + 3 = 85
