PASSAGE
The temperature T (in degrees Celsius) in a chemical reaction follows the equation T = 25 + 30ln(t), where t is time in minutes. For safety reasons, the reaction must be stopped when the temperature reaches 85°C.
When solving 25+30ln⁡(t)=8525 + 30\ln(t) = 85 for the stopping time, a student gets t=e2≈7.39t = e^2 \approx 7.39 minutes. However, the reaction chamber can only maintain controlled conditions for a maximum of 6 minutes. What is the most accurate interpretation of this mathematical solution?
