Max flew from Manchester to When he left Manchester the
New York in January 2010
temperature was -3oC
5
C = 9 𝐹 − 32
When he arrived in New York
the temperature was 23oF
Both temperatures need to
be in oF or oC. Decide which
you will do.
Substitute in to one of the
formula.
Or substitute -3oC into
F = 1.8C + 32
To get both temperatures in oF
Subtract one from the other
to get the difference
Which city was colder and
what was the difference in
the temperatures?
F = 1.8C + 32
Either substitute 23oF into
5
C = 9 𝐹 − 32
To get both temperatures in oC
