The motorboat travelled 4.92 metres during its acceleration

Explanation:

Let West be the positive direction and East be the negative. Since there are no components in the North or South directions, they can be ignored.

Let #v# = final velocity
#u# = initial velocity
#s# = displacement
#a# = acceleration

From the question
#v# = 3.6
#u# = 5.8
#a# = -2.1
#s# = Unknown

#v^2=u^2+2as#
#3.6^2=5.8^2+2*(-2.1)*s#
#-20.68=-4.2s#
#s=4.92# m
