Answer:
To solve this problem, we need to calculate the change in temperature between noon and 3:30 p.m. and then divide that by the number of hours between noon and 3:30 p.m.
Let's say the temperature at noon was 70 degrees F and the temperature at 3:30 p.m. was 75 degrees F.
The change in temperature between noon and 3:30 p.m. is 75 - 70 = 5 degrees F.
The number of hours between noon and 3:30 p.m. is 3.5 hours.
Therefore, the rate of change in temperature between noon and 3:30 p.m. is 5 degrees F / 3.5 hours = 1.43 degrees F per hour.
