Sagot :
Queremos encontrar la velocidad promedio de un automóvil dado que conocemos cuanto se desplaza y cuanto tarda en realizar ese desplazamiento. Veremos que la velocidad promedio es 45.3 millas por hora.
Recordar que definimos velocidad promedio como el cociente entre la distancia recorrida y el tiempo que se tarda en recorrer esa distancia.
Aca tenemos:
Desplazamiento = (30 + 1/5) cm
Tiempo = (2/3 horas)
Entonces la velocidad esta dada por:
[tex]V = \frac{(30 + 1/5)mi}{2/3 h} = \frac{(151/5)mi}{2/3 h} = 45.3 mi/h[/tex]
Asi podemos concluir que la velocidad promedio es 45.3 millas por hora.

The speed of the automobile is 45.3 miles per hour
The formula for calculating the speed of the automobile is expressed as:
- Speed = Distance/Time
Given the following parameters:
- Distances = 30.2 miles
- Time = 2/3 hour
Substitute into the formula:
Speed = 30.2 * 3/2
Speed = 15.1 * 3
Speed = 45.3 miles/hr
Hence the speed of the automobile is 45.3 miles per hour
