Question

Salma is filling her water jugs with spring water at the supermarket. The above equation gives the empty space in her jugs, VVV, in US gallons, after ttt minutes at a constant fill rate. How many minutes will it take to fill the jugs?

Answer 1

Answer:6.4 minutes ( or 6 minutes and 24 seconds)

Step-by-step explanation:Filling up the jug means the empty space is 0, hence V = 0.

We plug in 0 into V and solve for t to get the time required to fill it up:

Hence it will take 6.4 minutes to fill up the jugs.

Note: 0.4 minutes in seconds is seconds
