Question

The coldest temperature ever recorded in Mathville was -18°F. This happened on January 30th, 1964. The normal low for that day is 28 °F. How much colder was the record temperature than the normal low temperature?

Answer 1

It is given that the normal low is 28 F.

The temperature on that day was -18 F.

So the difference in temperature is:

$28-(-18)=46$

Hence the temperature was 46 F colder than the normal low temperature.
