Question
A solution is to be kept between 30°C and 35°C. What is the range of temperature in degree Fahrenheit?
Solution
Let x degree Fahrenheit be the temperature of the solution.
Then, `30° C< x° F < 35° C`
Now,` f = 9/5 C +32`
⇒`9/5xx30+32< x° F < 9/5xx35+32`
⇒` 54+32<x63+32`
⇒ `86° < x° < 95°`
Hence, the range of the temperature in Fahrenheit is between 86° and 95°.
