Answer:
-11 degrees
Step-by-step explanation:
At 7 am the temperature is 1 degrees, then, an hour later, its drops by 3 degrees (1-3) which equals -2 degrees, then it drops by 3 again, (-2-3), making it -5, then it drops again, (-5-3), making it -8 degrees, and then it drops one last time, (-8-3), making it -11 degrees.
(P.s, I hope this is Celsius)
