The speed of the falcon is 144 km/h
Explanation:
The speed of a body is a scalar quantity telling how fast the object is moving, without giving any information about its direction.
It can be calculated as:

where
d is the distance covered
t is the time taken
In this problem, the falcon has a speed of

We want to convert it into km/h. Let's keep in mind that:
1 km = 1000 m
1 h = 3600 s
Therefore, we convert as follows:
