To find the temperature at 10:00 P.M., we need to calculate the total decrease in temperature from 4:00 P.M. to 10:00 P.M.
6 hours passed from 4:00 PM to 10:00 PM.
Total decrease in temperature = 2.5ºC/hour * 6 hours = 15ºC
Starting temperature at 4:00 PM = 8ºC
Temperature at 10:00 PM = 8ºC - 15ºC = -7ºC
Therefore, the temperature at 10:00 P.M. was -7 degrees Celsius.
The outside temperature at 4:00 P.M. was 8 degrees Celsius. The temperature decreased 2.5ºC each hour until 10:00 P.M.
What was the temperature at 10:00 P.M.?
