(a)
A motorist is moving along a straight road with uniform acceleration. The motorist passes a village $X$ with a velocity of $8\text{ m s}^{-1}$ and another village $Z$ with a velocity of $13\text{ m s}^{-1}$ . The distance between $X$ and $Z$ is $2700\text{ m}$ . If village $Y$ is the midpoint of the distance between $X$ and $Z$ , find, correct to the nearest whole number, the time taken by the motorist to move from $X$ to $Z$ .
