I got 13:30 and 16:30 as per my graph and kept my answer like that because the graph does not have a sufficient level of accuracy to give you something like 13:29 or 16:29. You will probably still get the mark though . Good luck with the rest of your exams.
for the maths igcse paper 4h may 2012,
for Q 3c) do you think that they'd accept times of 13:29 and 16:29 due to the fact that there is no definitive answer so they may have a margin for error of +- 2 or something? any thoughts?
