Question

Write and solve an equation to determine how many degrees the temperature TT fell. The temperature at 5 P.M. is 20∘20∘

Answer 1

In order to determine the temperature drop per hour, we use the formula:

Rate of drop = (final temperature - initial temperature) / (final time - initial time)

Rate of temp drop = (-5 - 20) / (10 - 5)
Rate of temp drop = -25 / 5

The temperature dropped at a rate of -5 °F per hour.
