Условие

A boat of a length of 5 m and a mass of 120 kg is at rest in still water. An 80 kg sailor is walking in the boat from one end to the other. Find the distance in meters which the boat would move relative to the shore when the sailor reaches the boat end. The friction between the boat and water is negligible.

The answer should be given in the SI units unless otherwise stated. If the numerical result turns out to be an integer, it should be given as the answer. Otherwise round the result to the first decimal.
$g = 10\ \mathrm{m/s^2}$.
