Answer:
A.It’s not moving.
Explanation:
Position-Time graphs display the motion of a object by showing the changes of velocity with respect to time.
The motion of a car on a position-time graph that is represented with a horizontal line indicates that the car has stopped moving.
A straight line with a positive slope indicates that the car is moving at a constant velocity, and thus the slope is constant. On the other hand, a curve with a changing slope, shows that the velocity is changing.

Answer:
1,609
Explanation:
1 mile it's equal to 1,609 km
Doing the maths:
![25 mile * \frac{1,609 km}{1mile} =40,23[km]](https://tex.z-dn.net/?f=25%20mile%20%2A%20%5Cfrac%7B1%2C609%20km%7D%7B1mile%7D%20%3D40%2C23%5Bkm%5D)
D. 5 m/s
This is because the formula to find the speed of a wave is the wavelength divided by the period (wavelength/period). Since the wavelength is 100 m and the period is 20 s, the speed is 5 m/s.
If you are confused on the units, then think about it this way: If you put this problem in fraction form, it would be: 100 m/20 s. 100 divided by 20 is 5, but m and s are still there. Remember that this "/" is also a division symbol. Therefore, the unit will be m/s
