Question

If the water continues to drain at this rate until it is empty, how many total minutes will it take Paula to drain her fish tank?

Explain how you got your answer.

Answer 1

33-15=18 cm of water was gone in 6 min. so it’s draining 3cm/min.

She still has 15cm left to drain at 3cm/min. Is 5 more min. Total=11min.

Or 33 cm divided by 3 min=11 min
