it takes 3 hours to print a local newspaper using for printers;how long will it takes six printers to print the newspaper in the direct proportion step by step
Since the number of printers and the time taken to print the newspaper are in direct proportion, we can use the following equation:
(Printers) / (Time) = (Printers) / (Time)
Let's assume it takes 3 hours to print the newspaper using 4 printers. So, (4 printers) / (3 hours) = (6 printers) / (x hours).
Let's solve for x (the time taken with 6 printers):
(4/3) = (6/x)
Multiply both sides by 3x:
4x = 18
Divide both sides by 4:
x = 4.5
Therefore, it will take 6 printers approximately 4.5 hours to print the newspaper.
