Answer:
a. 55 hours
b. 1.9 degrees C
Step-by-step explanation:
This means for each hour the temperature drops 0.08. This is the expression 0.08x where x is number of hours.
a.) If the temperature has dropped 4.4, then 4.4 = 0.08x. Solving for x will give the number of hours it takes to drop 4.4.
4.4 = 0.08x
4.4 / 0.08 = x
55 = x
b.) If the temperature after 55 hours and dropping 4.4 is -2.5, then the temperature at the start would be -2.5 + 4.4 = 1.9. The temperature at noon was 1.9 degrees celsius.
