In November, the average temperature at the North Pole is -8.3​ Fahrenheit. In December, the average temperature at the North Pole is 7.7​ Fahrenheit colder than November's average temperature. In January, the average temperature at the North Pole is $1 1/4​​ times colder than December's average temperature.

What is the average temperature, in degrees Fahrenheit, at the North Pole in January?

1 answer

To find the average temperature at the North Pole in January, we first need to calculate December's average temperature.

December's average temperature = November's average temperature - 7.7
December's average temperature = -8.3 - 7.7
December's average temperature = -16

Next, we need to find January's average temperature which is 1 1/4 times colder than December's average temperature.

January's average temperature = December's average temperature * 1 1/4
January's average temperature = -16 * 1.25
January's average temperature = -20

Therefore, the average temperature at the North Pole in January is -20 degrees Fahrenheit.
