Question

A car has a displacement of 220 kilometers to the north in 3.5 hours. What is its velocity in kilometers per hour?​

Answer 1

Answer:

62.8km/hr

Step-by-step 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  = $\frac{displacement}{time taken}$

Insert the parameters and solve;

          Velocity  = $\frac{220}{3.5}$   = 62.8km/hr
