Cual será la velocidad de un móvil que recorre 4566m en 240 segundos?

Ithink it is letter b, i may be wrong but i think that is the answer

Answer the above statement is ( false );

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
