Explanation:

Average speed of car = 5m/s

Distance run by dog = 20m

Time taken = 5s

problem;

does the dog catches the car = ?

Solution;

let us determine speed of the dog;

Speed = $\frac{distance}{time} = \frac{20}{5}$ = 4m/s

The average speed of the car is 5m/s

Average speed of the dog is 4m/s

The dog is slower than the car and it will not catch the car at this rate.

Could an experiment similar to young's two-slit experiment be performed with sound? how might this be carried out? does it matte

Arada [10]

Young's double slit experiment(YDSE) can be used for any kind of waves such as electromagnetic waves, sound waves, water waves, gravity waves. YDSE is based on interference. In this experiment, we make two waves interfere in order to obtain bright and dark fringes on the screen(in case of light).
You can carry this out with water, would be great if you try this at pond or water reservoir in order to see perfect ripples.
