At what temperature on the Fahrenheit scale is the reading five times the reading on the Celsium scale?

Text Solution

Verified by Experts

Use the relation ltBrgt `(C)/(5)=(F-32)/(9)` and substitute `C=x^(@)C.F=5x^(@)F`
`(x)/(5)=(5x-32)/(9)`
`9x=25x-160`
`16x=160impliesx=(160)/(16)=10^(@)C`
the temperature in Fahrenheit scale is `5x=5xx10=50^(@)F`
