Answer:
3 obreros tardaran 225 minutos en completar el trabajo.
Step-by-step explanation:
Sea R la velocidad con la que un obrero puede construir 1 muro.
Sabemos que 15 obreros construyen un muro en 45 minutos, entonces:
(15*R)*45min = 1 muro
Con esta ecuación podemos encontrar el valor R
R = (1 muro)/(15*45min)
Ahora queremos saber cuando tiempo tardan 3 obreros en construir un muro, entonces tenemos que resolver:
(3*R)*T = 1 muro
Reemplazando el valor de R obtenemos:
(3*(1 muro)/(15*45min))*T = 1 muro
T = (1 muro)*(15*45 min)/(3*1 muro)
T = 5*45min = 225 min
3 obreros tardaran 225 minutos en completar el trabajo.
The answer to this question is D. I hope this helps
Answer:
the duration of the flight be 1 hour
Step-by-step explanation:
The computation of the duration of the flight is shown below:
Let us assume the duration of the flight be x hours
Now the equation would be
600 ÷ x - 600 x + (1 ÷ 2) = 200
600 ÷ x - 1200 ÷ 2x + 1 = 200
x(2x + 1) = 3
2x² + x - 3 = 0
(2x + 3)(x - 1) = 0
x = 1 hour
hence, the duration of the flight be 1 hour
The same is to be considered
Answer:
The slope of parallel lines area always the same, so the slope would just be your x, or 1/1

Answer:
D. Ant
Step-by-step explanation:
To find the speed in meters per minute, divide meters by minutes:
turtle: 6/5
snail: 4/8 = 1/2
caterpillar: 7/7 = 1
ant: 12/8 = 3/2 = 1.5
The ant traveled at a rate of 1.5 meters per minute.
