My daughter has had a go at this question this evening, she thought the answer was 1.5 and I agree.. however the 3 marks are given for 1, and only 1 mark given for her answer.

What have we missed?

Thank you

We just did 3/2… she sees now what she should have done, it’s been a while since I’ve done something like this.

It would be useful for her to look at other graphs in science - as these questions come up.

The tangent / the gradient is rate of change. Those questions do come up in GCSE science
