From midnight to 6:00 am, the temperature rose 8 degrees c. at 6:00 am, the temperature was -20 degrees c. What was the temperature at midnight?
( I DON'T UNDERSTAND! PLZ SHOW ME)
Tmidnight+8C/hr*6hrs=-20
Tmidnite=-20c-48c
Dang, it was cold at midnight.
Ok, I agree with MS Sue, I read it as rose 8C per hour. Bad reading.
=-20
thats all i had to do?
What was the temperature at midnight, Sparkles?
-20?
-20 + -8 = -28 C at midnight
At 6:00 am, the temperature was -20° C
after having risen 8° since midnight
So at midnight it was -28°
(years ago that would have been just a nippy night. These last few years it never got that cold in my part of Canada)
