Please Answer ASAP: As storm clouds gathered, the temperature fell 4 degrees in 3/4 of an hour. At what rate was the temperature falling? Simplify your answer and write it as a proper fraction, mixed number, or whole number.

Answer 1

Answer:

$5 \frac{1}{3}$ degrees per hour.

Step-by-step explanation:

If we know that the temperature fell 4 degrees in $\frac{3}{4}$ of an hour, we can set up a proportion to see how much fell in an hour.

$\frac{4}{0.75} = \frac{x}{1}$

$4 \cdot 1 = 4\\4 \div 0.75 = 5.\overline{33}$

$5.\overline{33}$ as a fraction is $5 \frac{1}{3}$.

So, the temperature fell at a rate of $5 \frac{1}{3}$  degrees per hour.
