Answer: -11 degrees Celsius

Step-by-step explanation:

4:00 am = -16 degrees

You know that 4:00am is four hours after midnight and you know that the temperature decreases by 1.75 degrees every hour so during that time it has dropped by:

1.75x4=7 degrees

Because it is -16 at 4:00am, you know it was 7 degrees higher at midnight

-16+7=-11

It was -11 degrees at midnight
