Question

A sponge filters water to eat microscopic food. A sponge can filter 8 liters of water in 10 hours or 12 liters in 15 hours. Is this relationship proportional?

Answer 1

Yes.

Explanation:

It is given that, A sponge can filter 8 liters of water in 10 hours or 12 liters in 15 hours.

8 L = 10 h

1 h =
`(10)/(8)` = 1.25 h

or

12 L = 15 h

1 h =
`(15)/(12)` = 1.25 h

Hence, this relationship is proportional.
