(a(i))[1]
Write an equation using $a$ and $p$ for the situation described.
(a(ii))[3]
Determine $a$ and $p$.
(b(i))[1]
Write an expression, in terms of $x$, for the time taken.
(b(ii)(a))[3]
Hence, show that $2x^2 - 7x + 2 = 0$.
(b(ii)(b))[4]
Determine the value of $x$. Show all working and give your answer correct to 2 decimal places.
