is the answer to this either 3/8 or ln(1/4) -27/8 by any chance?
Sorry not them, cant remember the answer now, but am pretty sure wasnt either of them, as i have put them in my calculator and remember not seeing them numbers

I was going through what I believe is this question today with my teacher (edexcel c4 textbook, review exercise, question 74) A) the diagram in the book is wrong, it should cross the x axis at (2,0) NOT 1,0 as it shows. B) I'm terrible at explaining, but the limits you use are the t values from part a) , 0.5 and 2. The explanation was something like all the values given, t is an increasing value, as shown in part b, so you are integrating the t values and you disregard the (x,y) graph. Hope that helped. ps, I've done all the past papers and have never seen a question like it

i used the limits 2 and 0.5 too, but my answer was wrong.
