Answer: I believe the answer would be 30.1 degrees
Explanation:
Since the temperature is dropping by 6.3 degrees per hour for 3 hours, this means that all we have to do is multiply 6.3 by 3 ( 6.3*3 ), which equals 18.9 so then all we do is subtract 18.9 from 49 ( 49-18.9 ) to get our answer, 30.1 degrees.
Hope this helps!
