Answer:

62.8km/hr

Explanation:

Given parameters:

Displacement = 220km due north

Time taken = 3.5hrs

Unknown:

Velocity in km/hr = ?

Solution:

Velocity is the rate of displacement per unit of time. This physical quantity is a vector which has both magnitude and directional attributes.

So, mathematically;

Velocity =
(displacement)/(time taken)

Insert the parameters and solve;

Velocity =
(220)/(3.5) = 62.8km/hr
