Answer:
77/12 degrees in one hour
Explanation:
To find how much the temperature of the compound rose in one hour, we need to find the temperature rise per hour.
Let's first find how much the temperature of the compound rises in 1 hour and 1/5 hour:
In 1 hour:
Temperature rise = 11/2 degrees
In 1/5 hour (12 minutes):
Temperature rise = (11/2) ÷ 6 = 11/12 degrees
Now, we can find the temperature rise per hour by adding the temperature rise in 1 hour and 1/5 hour:
Temperature rise per hour = 11/2 + 11/12
= (66/12 + 11/12) degrees
= 77/12 degrees
Therefore, the temperature of the compound rose 77/12 degrees in one hour.
