Ah 2015 paper. Try to understand the information provided in the question. The rate means how a variable changes with respect to time eg dX/dt, dY/dt, dV/dt etc. You’ll see that you’ll have dy/dx as both a function and a value so can just equate together solve for x.

You actually still remembered a 2015 paper...
Found it very familiar so I looked up my year’s paper. Last question paper 1, I remember looking at the graph and then realising my answer was wrong because I calculated value 4 for “a” which was obviously wrong haha.
