Question

In few climates, the range of temperatures may go to as much as ${20}^{\circ }$ Celsius in a single day. How much can these climates vary measured in degree Fahrenheit? ($F=\frac{9}{5}C+32$)

• A. ${20}^{\circ }F$
• B. ${36}^{\circ }F$
• C. ${62}^{\circ }F$
• D. ${68}^{\circ }F$

Answer 1

The correct option is D ${68}^{\circ }F$

We know that $F=\frac{9}{5}C+32$

Then Fahrenheit temp at ${20}^0$ is

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

$F=\frac{9}{5}\times 20+32=36+32={68}^0$
