Step-by-step explanation:
In order to describe speed of an object, we must describe the average speed of the entire trip. It is equal to the distance moved divided by time taken.
If a person covers a distance of 1 km to the library in 15 minutes, we can find its average speed.
Firstly, we convert 15 minutes to hour, 15 min = 0.25 hours
Now, using formula of speed = distance/time
It means that the average speed of the person is 4 km/h. Hence, the given statement is true.

Answer:
The vector will change in direction and decrease in magnitude
Step-by-step explanation:
Given:
vector multiplication by -π/4
-π/4= -0.785
Due to the negative sign "-", the, vector will change/reverse its direction.
And as of the magnitude, 0.785<1 hence the magnitude of vector will be decreased by this factor !
