Answer:
It will take 11 minutes to reach the required temperature.
Step-by-step explanation:
As the temperature is decreasing at a constant rate, it can be solved by linear algebra.
First we find out the difference in the original and required temperatures.
Difference=15-(-18)
Difference=15+18
Difference=33°C
The temperature is increasing constantly at a 3°C rate per minute. So, the equation formed is:
3x=33
x=33/3
x=11 minutes
