Answer:

11.6mph South East

Explanation:

Given parameters:

Time = 2.25hrs

Displacement  = 26.2miles south east

Unknown:

Velocity = ?

Solution:

Velocity is the displacement divided by the time taken. It is a vector quantity with both magnitude and direction.

 Now;

       Velocity  = [tex]\frac{displacement}{time taken}[/tex]

       Velocity  = [tex]\frac{26.2}{2.25}[/tex]   = 11.6mph South East
