Assume there is a smallest rational integer that has the following form: a/b
Then observe that we can define a/(b+1), which is strictly less than a/b because its divisor is bigger and is rational because it is the product of two numbers. Due to the contradiction created by our original claims that a/b is the smallest rational number that is possible, we might conclude that there is no such thing as the smallest rational number.
There can therefore be no smallest rational number because we may always define a smaller rational number than the one we now possess.
<h3>What is Rational number ?</h3>
Any number that can be expressed as a ratio is considered reasonable. It is therefore possible to represent it as a fraction when the numerator and denominator are both full numbers.

Answer:
a. El tiempo de recorrido es 
segundos para un objeto localizado a un metro de distancia de la cámara fotográfica.
b. El tiempo de recorrido es 0.118 segundos para un objeto localizado a un metro de distancia de la cámara fotográfica.
Explanation:
El sonido es un tipo de onda mecánica, que es un tipo de onda que necesita de un medio material para propagarse. En este caso, entendemos que el sonido se propaga a través del aire atmosférico hasta llegar a su destino y devolverse a rapidez constante. Entonces, podemos estimar el tiempo (
), medido en segundos, a partir de la siguiente fórmula:
Donde:
- Distancia entre la cámara fotográfica y el objeto, medida en metros.
- Rapidez del sonido en el aire atmosférico, medida en metros por segundo.
A continuación, calculamos el tiempo de recorrido:
a. (
, 
)
El tiempo de recorrido es segundos para un objeto localizado a un metro de distancia de la cámara fotográfica.
b. (
, )
El tiempo de recorrido es 0.118 segundos para un objeto localizado a un metro de distancia de la cámara fotográfica.
From the point of view of the northern hemisphere:
The sun starts out the year at the Spring equinox, March 21,
Right Ascension 0, Declination 0.
3 months later, Summer solstice, June 21
RA = 6 hours, Dec. = +23.5°
3 months later, Fall equinox, September 21,
RA = 12 hours, Dec. = 0
3 months later, Winter solstice, December 21,
RA = 18 hours, Dec. = -23.5°
Based on the scenario,
The thing that the result say about distance covered is :
it tells you that the distance covered is equal to the average speed times the travel time
hope this helps
