Ed spoke to his cousin in Australia, who told him it was 25°C

Question

Answer 1

To convert the temperature from degrees Celsius to degrees Fahrenheit using the formula $F=\frac{9}{5}C+32$:

Given that $C=25$:

$$F=\frac{9}{5}\times 25+32$$

Calculating $\frac{9}{5}\times 25$:

$$\frac{9\times 25}{5}=\frac{225}{5}=45$$

Now, add 32:

$$F=45+32=77$$

Therefore, the temperature in degrees Fahrenheit is $77°F$.
