Question

On January 22, 1943 the temperature in Spearfish, South Dakota fell from 53.6 degrees Fahrenheit to -4 degrees Fahrenheit in just 27 minutes. What was the total change in temperature??

Answer 1

-57.6 degrees

Explanation:

0 is a point between 53.6 degrees and -4 degrees.

The change from 53.6 to 0 was -53.6 degrees, and that from 0 to -4 degrees was -4 degrees.

Thus, the total change (drop) in temperature was -53.6 degrees less 4 degrees, or -57.6 degrees.
