the outside tempature ast 4:00 pm was 8 degrees celsius the tempature decreased 2.5 oCeach hour until 10:00pm what was the tempature at 10":00pm?
To find the temperature at 10:00 pm, we need to calculate the total decrease in temperature from 4:00 pm to 10:00 pm.
The total time between 4:00 pm and 10:00 pm is 6 hours (6 x 1 hour).
The decrease in temperature per hour is given as 2.5 degrees Celsius.
Therefore, the total decrease in temperature is 2.5 degrees Celsius/hour x 6 hours = 15 degrees Celsius.
Since the initial temperature was 8 degrees Celsius, and the temperature decreased by 15 degrees Celsius, the temperature at 10:00 pm would be 8 degrees Celsius - 15 degrees Celsius = -7 degrees Celsius.
To find the temperature at 10:00 pm, we need to calculate the decrease in temperature from 4:00 pm to 10:00 pm.
Given the temperature at 4:00 pm was 8 degrees Celsius, and the temperature decreased by 2.5 degrees Celsius per hour, we can calculate the total decrease in temperature over a span of 6 hours (from 4:00 pm to 10:00 pm):
Decrease in temperature = rate of temperature decrease * number of hours
= 2.5 degrees Celsius/hour * 6 hours
= 15 degrees Celsius
Now we need to subtract the decrease in temperature from the initial temperature at 4:00 pm to find the temperature at 10:00 pm:
Temperature at 10:00 pm = Initial temperature - Decrease in temperature
= 8 degrees Celsius - 15 degrees Celsius
= -7 degrees Celsius
Therefore, the temperature at 10:00 pm would be -7 degrees Celsius.
To find the temperature at 10:00 pm, you need to calculate the total decrease in temperature from 4:00 pm to 10:00 pm.
First, you need to determine the number of hours between 4:00 pm and 10:00 pm. Since there are 6 hours between these two times, we can calculate the total decrease by multiplying the decrease per hour (2.5 degrees Celsius) with the number of hours:
Total decrease = Decrease per hour * Number of hours
= 2.5°C/hour * 6 hours
= 15°C
Since the temperature at 4:00 pm was 8°C, we need to subtract the total decrease from this initial temperature to find the temperature at 10:00 pm:
Temperature at 10:00 pm = Initial temperature - Total decrease
= 8°C - 15°C
= -7°C
Therefore, the temperature at 10:00 pm is -7 degrees Celsius.
