Cornwalis, TN  was 340 at 6 am and by midnight it was -60.  Dubuter, MA was -60 at 6 am on the same day and by midnight it was -340.  Which town had a greater temperature change?  How do you know?

To determine which town experienced a greater temperature change, we need to calculate the change in temperature for both Cornwalis, TN, and Dubuter, MA.

### 1. Cornwalis, TN:
- **Starting temperature at 6 AM**: 340°F
- **Ending temperature at midnight**: -60°F

The temperature change is:
\[
\text{Change} = \text{Final temperature} - \text{Initial temperature} = -60 - 340 = -400
\]
So, the temperature change in Cornwalis, TN is **400°F**.

### 2. Dubuter, MA:
- **Starting temperature at 6 AM**: -60°F
- **Ending temperature at midnight**: -340°F

The temperature change is:
\[
\text{Change} = \text{Final temperature} - \text{Initial temperature} = -340 - (-60) = -340 + 60 = -280
\]
So, the temperature change in Dubuter, MA is **280°F**.

### Conclusion:
Cornwalis, TN experienced a greater temperature change (400°F) compared to Dubuter, MA (280°F).

We know this by calculating the absolute temperature differences between the starting and ending points in each town.
