Answer:
These quantities varies directly.
Step-by-step explanation:
Given the statement:
A mill processes 27 tons of flour in 3 hours.
If two quantities y and x have a nonzero, constant ratio k then they are said to be direct variation.
The amount of flour processed is directly proportional to time.
Also,
Number of tons of flour per hour = [tex]\frac{27}{3} = 9[/tex]
Therefore, these quantities vary directly with a constant ratio of 9.
