Question

If the temperature is 30 degree Celsius, then the temperature in Fahrenheit is .

• A. 76
• B. 86
• C. 56

Answer 1

The correct option is B 86

The linear equation that represents the relationship between temperature readings in Fahrenheit and Celsius is given by

$F=\frac{9}{5}C+32.$

Given that $C=30.$

$⟹F=\frac{9}{5}\times 30+32$
$⟹F=(9\times 6)+32=86$
Thus, the temperature in Fahrenheit is 86.
