Question 258719: The temperature range for a week in a mountain town was between 0-30 degrees Celsius. Find the temerature range in Fahrenheit degrees.
C=5/9F-32
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! you have the formula wrong for conversion from Fahrenheit to Celsius.
the correct formula is:
C = (5/9) * (F-32)
when F is 32 (freezing), C = 0 as it should be.
when F is 212 (boiling), C = 100 as it should be.
now that we have the correct formula for Centigrade, we can derive the correct formula for fahrenheit.
start with:
C = (5/9) * (F-32)
multiply both sides of this formula by (9/5) to get:
(9/5) * C = F - 32
add 32 to both sides of this formula to get:
(9/5) * C + 32 = F
formula for F is:
F = (9/5) * C + 32
to test this formula we use freezing and boiling points again.
F = (9/5) * 0 + 32 = 32 (freezing point).
F = (9/5) * 100 + 32 = 180 + 32 = 212 (boiling point).
formula is good and we can use it to solve the problem.
when C = 0, F = 32 which we already solved.
when C = 30, F = (9/5) * 30 + 32 = 54 + 32 = 86.
your answer is
temperature range in celsius is 0 to 30.
equivalent temperature range in fahrenheit is 32 to 86.
