Step-by-step explanation:
Each 30 minutes, we have a change of -0.75
So in an hour , we will have a change of -0.75 * 2 = -1.5
since -2.1 is greater than -4.6, this indicates that it was a time before 6:45 PM
so, let us find the temperature drop
That would be;
-2.1-(-4.6) = -2.1 + 4.6 = 2.5
So let us find the number of half hours
That would be;
2.5/0.75 = 3 1/3 half hours
3 half hours is 90 minutes
1/3 half hour is 1/3 * 30 = 10 minutes
Total number of minutes is;
90 + 10 = 100 minutes
So let us count 100 minutes before 6:45 PM
120 minutes before would be;
4:45 PM
but we want 100 minutes, so we have to add 20 minutes
That would be;
4:45 PM + 20 minutes
= 4:65 which is 5 : 05 PM
