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

Answer 1

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.
