Question

calculate the temperature at which the reading on the fahrenheit scale is double the reading on Celsius scale

Answer 1

The temperature will 160'celsius
at which the temperature on fahrenheit will be double the celsius scale that is" 320'celsius"

hope it helps......

Answer 2

let the reading in Celsius scale = C
the reading in Fahrenheit scale = F


the reading on the fahrenheit scale is double the reading on Celsius scale
So F = 2C

we know that
F = 32 + 9C/5

or 2C = 32 + 9C/5

or 2C - 9C/5 = 32

or (10C - 9C)/5 = 32

or C/5 = 32

or C = 32×5 = 160℃

F = 2C = 160×2 = 320°F

So the temperature is 160℃ or 320°F
