<u>Solu</u><u>tion</u><u>:</u>
We are given,
- Distance = d = 45 m
- Time = t = 24 s
Speed is given by:
Putting the given values,
s = (45 m)/(24 s)
=> s = 1.875 m/s

The substances which occupies mass or volume occupying space is known as matter. It comprises of those things that can be seen through the eyes and it may include things like water, plants, food, dresses, etc. It can be defined by color or hardness.
The substances that are made of energy without occupying space is known as non-matter substances. It can be classified as form of some energy. Some examples include light energy from torch, heat energy from fire and sound energy form whistle, etc.
If a photon has a wavelength of about 10^-10 meters, it would be certainly in the X rays region and it would have a frequency of 2.99792458x10^18 Hz, that you can easily calculate using the relation that states that the product of the wavelength and the frequency of an electromagnetic wave aka light is always equal to 299,792,458 m/s which is the exact value of the speed of light!
