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:

V = \frac{(30 + 1/5)mi}{2/3 h} = \frac{(151/5)mi}{2/3 h} = 45.3 mi/h

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

The value of a car is $30,000 and depreciates at a rate of 6.5% each year.
navik [9.2K]

Answer:$20250

Step-by-step explanation:

6.5% of 30000

6.5/100 x 30000

(6.5 x 30000)/100

195000/100=1950

First year depreciation 30000-1950=28050

Second year=28050-1950=26100

Third year=26100-1950=24150

Fourth year=24150-1950=22200

Fifth year=22200-1950=20250
