Question

The temperature was -5.5°F at 9 A.M. Then the temperature dropped 5 degrees per hour for the next 3 hours. What was the temperature at noon? A -20.5°F B -10.5°F C 10.5°F D 20.5°F

Answer 1

a -20.5 degrees f

Step-by-step explanation:

9 and 12 pm are 3 hours apart

that means that the temperature dropped 3 * 5 degrees

3 * 5 is 15

you subtract that from -5.5

-5.5 - 15 = -20.5

it is a -20.5 degrees fahrenheit
