The amount of time t(in minutes) that it takes to put out a fire varies inversely with G, the volume of water used (in hundreds of gallons). When G is 2, t is 20. Find how long it takes to put out a fire when 500 gallons of water (G = 5) are used.

Respuesta :

Answer:

50 minutes.

Step-by-step explanation:

You can use a ratio to solve:

    [tex]t[/tex]     :     [tex]G[/tex]

  20    :     2

   10    :     1

    [tex]x[/tex]     :     5

[tex]x[/tex] must be 50 minutes since 100 gallons of water takes 10 minutes.
