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 Question 6a Additional Specimen Paper 3 The shaded cards are questions to help you get to your final answer. Try to work out the order to answer them in…then answer them!
