Question

A environmental scientist buys 20 gallons of oil eating bacteria to help remediate an area affected by an oil spill. The volume of water the scientist wants to cover with this bacteria is 5 ft³. What volume of water can the scientist cover with the bacteria she purchased? (1 gal = 0.13 ft³)

Answer 1

• 2.6 ft³

Explanation:

Let the required volume be x

Use the ratio of gallon/volume to solve:

• 1/0.13 = 20/x
• x = 20*0.13
• x = 2.6 ft³

With 20 gallons the scientist can cover 2.6 ft³ of water volume
