Answer:

12 minutes.

Explanation:

This problem can be solved through the use of a linear function. The basic equation of a linear function is:

y = mx + b

In this scenario, m will be replaced with 2.5 as it is the rate of which the water is filling per minute. y will be replaced with 30 as that is the amount of water we need to fill. This equation does not have any value for b since b would represent any water that the tub has in it before timing which it had none. x will represent the amount of time that it will take to fill 30 liters. You should get this equation:

30 = 2.5x

Divide both sides by 2.5

x = 12

This means that it will take 12 minutes to fill 30 liters.

~Hope this Helps!~
