ASAP! The graph shows outdoor temperatures (F) recorded one fall evening in Ohio. At what rate did the temperature change during
this time interval?
A, -3F/minute
B, -4F/hour
C, -5F/minute
D, -3F/hour
1 answer:
Your answer would be D) -3°F/hour
Look at it this way...
47°F at 7:20pm
46°F at 7:40pm
45°F at 8:00pm
44°F at 8:20pm
43°F at 8:40pm
The temperature is going down by 1°F every 20 minutes so...
-1°F/20 minutes
Obviously there's no answer choice that says that so you'd need to change the minutes into an hour...
So an hour is 60 minutes and 60/20 = 3
So if you do 3・-1
You get the answer... -3°F/hour
