Respuesta :

fichoh

Respuesta:

25 días

Explicación paso a paso:

Dado :

escenario 1

Área = 600 m

Número de días = 12

Número de trabajadores = 30

Tasa = 6

Escenario 2:

Área = 900 m

Número de días = n

Número de trabajadores = 36

Tasa = 6

Igualar los parámetros en cada escenario:

12 / n = 36/30 * 6/10 * 600/900

12 / n = 6/5 * 3/5 * 2/3

12 / n = 6/5 * 1/5 * 2/1

12 / n = 12/25

12 * 25 = 12n

300 = 12n

n = 300/12

n = 25 días

The number of days that 36 workers need at the given rate is 25 days

From the given question, we have 2 scenarios

First case:

  • Distance worked = 600m
  • Number of workers = 30 workers
  • Days of wors = 12 days
  • Rate per day = 10 hours per day

Second case:

  • Distance worked = 900m
  • Number of workers = 36 workers
  • Days of wors = n days
  • Rate per day = 6 hours per day

Taking the ratios of the distance worked, the number of workers, and rate will give:

12/n = 36/30 * 6/10 * 600/900  

12/n = 129600/270000

Cross multiply;

129600n = 12 * 270000

129600n = 3240000

n = 3240000/129600

n = 25

Hence the number of days that 36 workers need at the given rate is 25 days
