I had no idea what to do for d (ii)
I just did 0.4 x 10 = 4m = 4L LOL I'm pretty sure that's not correct.

Oh crap. I think I understand now.. is it 4m, so thus we divide our answer in (i) by 3?!?! ok no idk.

I integrated the found rate
SO V=0.4t + 38( or what ever the answer from i was cant remember what i got)
Then just throw in t=10

i forgot my answer but you use Sum of AP.
a = 3 d=2

T(20) = 3 + 2(19) = 41
S(20)=10(44) = 440
