Answer:
The temperature changed by 8 degrees
Explanation:
From the question you are told that the temperature rises 2 degrees per hour. This can be expressed as;
2 degrees = 1 hour
We are to find the change in temperature after 5 hours, this is expressed as:
x = 5 hours
Divide both expressions
2/x = 1/5
x = 2 * 5
x = 10 hours
The temperature change = Final temp - Initial temp
Temperature change = 10 - 2 = 8 degrees
Hence the temperature changed by 8 degrees .
