8.1km/hr due North

Explanation:

Given parameters:

Displacement = 20 miles North

Time = 4hours

Unknown;

Velocity = ?

Solution:

Velocity is the speed in a particular direction. It is simply displacement divided by time. A change in position with time.

Velocity = $\frac{displacement}{time}$

The unit is usually expressed in km/hr or m/s

We need to convert the given displacement to that in km:

1 mile = 1.609km

20miles = 1.609 x 20, 32.18km

Velocity = $\frac{32.18}{4}$ = 8.1km/hr due North
