Question

A plane traveled west for 4.0 hours and covered a distance of 4,400 kilometers. What was its velocity?

Answer 1

Answer:

The velocity is 1,100 $\frac{km}{h}$

Explanation:

Velocity ​​is associated with the change of position of a body over time. In other words, velocity expresses the relationship between the space traveled by an object, the time taken for it and its direction.

So, since velocity considers the direction in which the displacement of an object occurs, it is considered a vector magnitude. In other words, in the velocity it is necessary to take into account also the direction of the mentioned displacement.

In other words, velocity implies the change of position of an object in space within a certain amount of time (that is, speed), added to the direction in which said movement occurs.

The velocity can then be calculated as the displacement (difference between end and initial point) divided by time. Its unit of measure in the International System (S.I.) is the meter per second (m / s). Although the speed can also have units of km / h.

So, in this case:

$velocity=\frac{4,400 kilometers}{4 hours}$

velocity=1,100 $\frac{km}{h}$

The velocity is 1,100 $\frac{km}{h}$

Answer 2

It’s should be 17600
