A roach named Daniel and a donkey named Luke had a bet going to see who was the fastest. Each agreed to run a 500 m race to see who was the fastest. Luke ran as fast
as he could at a speed of 0.3m/s for the whole race. Daniel, thinking he is so fast, ran
a much different race. Daniel ran the first 100m at 2.2 m/s, then he got tired so he
stopped for some water and to catch his breath, which took 30 minutes. Feeling
refreshed, he ran the last 400 m with an average speed of 2.9 m/s.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
