The boat's position
x relative to its starting point
x_0=0 is determined by


x=x_0+v_0t+\frac12at^2

where
v_0 is its initial velocity,
a is its acceleration, and
t is time. After
t=6\,\mathrm s, the boat has traveled


x=\left(2.5\,(\mathrm m)/(\mathrm s)\right)(6\,\mathrm s)+\frac12\left(4.2\,(\mathrm m)/(\mathrm s^2)\right)(6\,\mathrm s)^2


\implies x=91\,\mathrm m
