The average will increase by 5 points, therefore, option c is correct!
Answer:
3 hours
Step-by-step explanation:
The temperature change after an hour shows an increase of 5 degrees. To calculate how long it takes to reach 60 degrees, we first find the difference from the current temperature to 60 degrees.
60 - 45 = 15 degrees
Since a rise of 5 degrees occurs in one hour, we divide 15 by 5 to find out how many hours are needed to reach 60 degrees.
15 / 5 = 3 hours
