running at their respective constant rates, machine x takes 2 days longer to produce w widgets than machine y. at these rates, if the two machines together produce 5 4 w widgets in 3 days, how many days would it take machine x alone to produce 2w widgets?
According to the given statement It will take 8/5 days for machine x alone to produce 2w widgets.
What is machine?A machine is a mechanical device that helps to reduce human effort and increase efficiency. It can be used to automate processes, reduce physical labor, and produce complex products. Machines can be powered by manual, electric, hydraulic, and pneumatic means.
Let x and y be the rates of production of machines x and y respectively.
Then, the rate of combined production of the two machines is x + y.
Given that machine x takes 2 days longer than machine y to produce w widgets, we can say that x = y + w/2.
Also given that the two machines together produce 5w widgets in 3 days, we can say:
(x + y) * 3 = 5w
Substituting x = y + w/2 in the above equation, we get:
(y + w/2 + y) * 3 = 5w
Solving for y, we get:
y = 5w/6
Therefore, the rate of production of machine x is:
x = 5w/6 + w/2
Now, to find the time taken by machine x alone to produce 2w widgets, we can use the equation:
Time taken = (2w)/x
Substituting x = 5w/6 + w/2, we get:
Time taken = (2w)/(5w/6 + w/2)
Simplifying, we get:
Time taken = 8/5 days
Therefore, it will take 8/5 days for machine x alone to produce 2w widgets.
