Question
A thermometer reading 7 degrees C is brought into a room with a constant temperature of 29 degrees C.
If the thermometer reads 15 degrees C after 4 minutes, what will it read in 6 minutes? 11 minutes?
If the thermometer reads 15 degrees C after 4 minutes, what will it read in 6 minutes? 11 minutes?

There has to be more to this question.
Are we to assume Newton's Law of "Cooling" or
are you assuming the change is linear ?
If linear, then it changed 8° in 4 min, or 2° per minute
so after 6 minutes, it would change 12° to read 19°
after 11 minutes, it would change 22° and read 29° which was the original room temperature.
Such a change would not happen in reality, it would follow the laws discovered by Newton, and would require Calculus.
