Starting at noon, the temperature dropped steadily at a rate of 0.8 degrees celsius every hour. How many hours did it take for the temperature to decrease by 4.4 degrees Celsius?

For this case we have that the temperature drops steadily at a speed of , that is, every hour drops 0.8 degrees. So, we can propose a rule of three:

1 hour ----------> 0.8 degrees

x ------------------> 4.4 degrees

Where the variable "x" represents the number of hours that must pass for the temperature to decrease by 4.4 degrees.

Thus, for the temperature to decrease by 4.4 degrees, 5.5 hours must pass.
