Answer: V = L (k)

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

  • <em>Volume of a box = V </em>
  • <em>Length = l </em>
  • <em>Constant of proportionality = k</em>

We know that the volume of the box (V) varies directly with its length (l).

So, the expression for the volume is:

V = L (k)

Olivia takes twelve laps on a long track in fifteen minutes. how much time will it take her to skate thirty laps ?
Firdavs [7]

Answer:

C. 37.5 minutes


Step-by-step explanation:

You can set up a proportion to help you figure this out.

12/15=30/x (in this proportion, the number of laps are both on the numerator and the time it takes her is on the denomiator.)

Now, just cross multiply and your equations should be: 12·x=15·30, which equals to 12x=450.

Divide 12 on both sides and x=37.5
