Question

Starting at noon, the temperature dropped steadily at a rate of 0.8 degrees Celsius every hour. For each of these situations, write and solve an equation and describe what your variable represents. a. How many hours did it take for the temperature to decrease by 4.4 degrees Celsius?

Answer 1

5.5 hours

Explanation:

For every 1 hour, there is a 0.8 degrees Celsius drop in temperature.

Let "t" represent the total amount of temperature dropped.

Let "h" represent the number of hours

The given scenario can be represented with the equation below:

`t = 0.8h`

To find the number of hours (h), it takes for the temperature to decrease by 4.4 degrees Celsius, plug in the value of t in the equation, and solve for h.

`t = 0.8h`

`4.4 = 0.8h`

Divide both sides by 0.8

`5.5 = h`

It would take 5.5 hours for the temperature to decrease by 4.4 degrees Celsius.
