Question

If it is 40 degrees Celsius, what is the temperature in Fahrenheit?

A. 40 degrees
B. 104 degrees
C. 54 degrees
D. 102 degrees

Answer 1

104 = B

Explanation:

A quick way to do this is to use this formula

• F = 2*C + 30
• C = 40
• F = 2*40 + 30
• F = 80 + 30
• F = 110

Since this is an estimate, you are only guided to whether your answer is correct or not. Here's the actual formula

• F = (9/5) * 40 + 32
• F = 360/5 + 32
• F = 72 + 32
• F = 104
