Question

Calculate the temperature at which the reading on the Degree Fahrenheit scale is double the reading of degree Celsius scale..(with proper steps)

Answer 1

by the given condition F=2C
we know F=9/5C+32
=1.8C+32
then 2C=1.8C+32
2C-1.8C=32
0.2C=32
C=32/0.2
=320/2
=160.
at 320F temperature of Fahrenheit scale is twice of Celsius scale.
