8. Question 6a Additional Specimen Paper 3
Max flew from Manchester to New York in January 2010
When he left Manchester the temperature was -3oC
Which city was colder and what was the difference in the temperatures?
C = 𝐹 −32
When he arrived in New York the temperature was 23oF
F = 1.8C + 32
Both temperatures need to be in oF or oC. Decide which you will do.
Substitute in to one of the formula.
Either substitute 23oF into
To get both temperatures in oC
Or substitute -3oC into
To get both temperatures in oF
Subtract one from the other to get the difference
