Your answer is that at noon, the temperature in New York was positive 5 degrees Celsius.
From 8pm-midnight there are 8 hours. So 1.5 X8= 12, so -5 -12= - 17
between midight and 10am there are 10 hours. so 2 x 10=20.
so -17 + 20= +3
than -4= -1
-1
PS. NEVERMIND I WAS WRONG IN GETTING THE ANSWER, THERE IS 4 HOURS BETWEEN 8 AND MIDNIGHT, I DONT KNOW WHAT I WAS THINKING, BUT THE FORMULA IS CORRECT.
-5 - (1.5 times 4 hours ) + (10 times 2) -4
-5 -6 +20 -4
5 degree celcius
