What is the change in temperature when the starting temperature is 185°F and the current temperature is 140°F?

To determine the change in temperature, you need to subtract the current temperature from the starting temperature. In this scenario, the starting temperature is 185°F, and the current temperature is 140°F.

Calculating the change in temperature involves this simple formula:

Change in Temperature = Starting Temperature - Current Temperature

Substituting the values gives:

Change in Temperature = 185°F - 140°F = 45°F

This computation indicates that the temperature has dropped by 45°F. Therefore, the correct answer reflects the actual calculated difference in temperature, demonstrating a clear understanding of how to measure changes in temperature accurately with a specific focus on basic subtraction in temperature readings.
