Question

James fish tank has 19 L of water in it she plans to add 6 L per minute until the tank has at least 67 L. write inequality that can be determined the possible number of minutes Jane could add water. Use t for the number of minutes.

Answer 1

Explanation:

The starting amount of water in the tank = 19

She needs to add enough water to get 67L of water in the tank.

19 + 6*t ≥ 67 Subtract 19 from both sides.

19-19 + 6t ≥ 67 -19

6t ≥ 68 Divide by 6

t ≥ 68/6

t ≥ 11.33 minutes
