A solution is to be kept between 40°C and 45°C. What is the range of temperature in degree Fahrenheit, if the conversion formula is  F=\frac{9}{5}C+32

Answers (1)

Given: The solution should be kept between 400C & 450C

Now, let C be the temp in Celsius & F be the temp in Fahrenheit.

Thus, 40 < C < 45

On multiplying each term by 9/5,

72 < 9/5 C < 81

Now, add 32 to each term,

104 < 9/5 C + 32 < 113

Thus, 104 < F < 113

Therefore, F i.e., temp in Fahrenheit should be between 1040F & 1130F.
