Answer
Please see the work below.
Work Step by Step
We know that
(a) $a=\frac{\Delta v}{\Delta t}$
We plug in the known values to obtain:
$a=\frac{\frac{110}{3.6}}{(1.2)\times(60)}$
$a=0.42\frac{m}{s^2}$
(b) We know that the direction of acceleration is opposite to that of the speed.
(c) As $x=\frac{v^2}{2a}$
We plug in the known values to obtain:
$x=\frac{(\frac{110}{3.6})^2}{2(0.42)}$
$x=1100m$
