Answer:

  • 2.5 gallons per minute

Step-by-step explanation:

Proportional relationship is determined by the equation:

  • y = kx, where k is the coefficient of proportionality

We have:

  • y = 0.5 and x = 0.2

Substitute the values into above equation and solve for k:

  • 0.5 = 0.2k
  • k = 0.5/0.2
  • k = 2.5

Answer:

2.5

Step-by-step explanation:

Let,

Constant of proportionality = x

0.5 = 0.2 × x

0.5/0.2 = x

5/2 = x

2.5 = x

Hence,

Constant of proportionality is 2.5
