Question

The temperature at midnight was -2ºF. During the next 4 hours, a decrease of 4ºF was recorded. What was the temperature at 4am? Add unit of measure!*

Answer 1

The temperature at 4am after a decrease of 4ºF from an initial temperature of -2ºF would be -6ºF.

Step-by-step explanation:

If the temperature at midnight was -2ºF and during the next 4 hours there was a decrease of 4ºF, the temperature at 4am can be determined by subtracting the decrease from the initial temperature. Therefore:

Initial temperature = -2ºF
Temperature decrease = 4ºF

The new temperature = Initial temperature - Temperature decrease
= (-2ºF) - (4ºF)
= -6ºF

So, the temperature at 4am was -6ºF.
