The Sahara desert is one of the warmest places on the earth. It is said that the highest temperature ever recorded in the Sahara was about 58 Celcius degrees back in 1922. To the nearest integer, what was this temperature in degrees Fahrenheit?

The relationship between degrees Celcius and degrees Farenheit is given by the formula.
\( \frac{\mathrm{C} }{\mathrm{5}} = \frac{\mathrm{F-32} }{\mathrm{9}} \Rightarrow \frac{\mathrm{58} }{\mathrm{5}} = \frac{\mathrm{F-32} }{\mathrm{9}} \Rightarrow 11.6=\frac{\mathrm{F-32} }{\mathrm{9}}\)
Multiplying both sides by 9 we get:
\(F - 32 = 11.6 \times 9 = 104.4\)
Add 32 to both sides to get:
\(F =104.4 + 32 =136.4 ≈136\) (to the nearest integer)
