One winter night the temperature dropped 3 degrees every hour. If the temperature was 0 degrees at midnight,what was the temperature at 4:00 am?
How many hours are between midnight and 4:00 AM? At three degrees per hour, times how many hours? Subtract from zero degrees.
By the way, the answer will be the same in every school. If you have a math question, put that in the school SUBJECT line. Math is the same in every school. Unless you are studying that particular school as a school SUBJECT.
To find the temperature at 4:00 am, we need to determine how many hours have passed from midnight.
Since the temperature dropped 3 degrees every hour, we can calculate the number of hours passed by subtracting the starting time (midnight) from the target time (4:00 am).
There are 4 hours from midnight to 4:00 am, so we multiply 4 by 3 to find the total temperature drop: 4 hours * 3 degrees per hour = 12 degrees.
Next, we need to subtract the temperature drop from the starting temperature at midnight (0 degrees).
0 degrees - 12 degrees = -12 degrees.
Therefore, the temperature at 4:00 am would be -12 degrees.
