Question

CAVES The temperature inside Mammoth Cave in Kentucky is about

12.2°C year round. If the temperature outside the cave is -2.4°C,
what is the change in temperature from outside to inside the cave?

Answer 1

14.6°C

Explanation:

Method 1

Higher value - lower value

12.2°C - (-2.4°C) *two negatives make a positive

12.2 + 2.4

14.6°C

Method 2

-2.4°C to 0°C = 2.4 increase (+2.4°C)

0°C to 12.2°C = 12.2 increase (+12.2°C)

Total change = 12.2 + 2.4= 14.6°C
