The temperature of coffee, T (in degrees Celsius), as it cools can be expressed as a factor of time, r, in minutes, by the equation 20. Coffee is safe to drink at 45 °C. Approximately how long will it take the coffee to cool down to 45 °C? (Round final solution to 2 decimal places.) T=79(0.85) +20, where t [4 marks] The temperature of coffee, T (in degrees Celsius), as it cools can be expressed as a factor of time, r, in minutes, by the equation 20.
