Question

The average temperature in Fairbanks, Alaska, was —4°F one day and

16°F the next day. Find the difference of the temperatures.

Answer 1

• 20°

Explanation:

We know that:

• -4 + x = 16 [x = difference between two temperatures]

Solution:

• -4 + x = 16
• => x = 16 + 4
• => x = 20

Hence, the difference between the two temperatures is 20°.
