Question

The time that a dolphin can hold its breath underwater compared to the time a penguin can hold its breath underwater is represented by the ratio 3 to 4. If a penguin can hold its breath for 20 minutes, how long can a dolphin hold its breath underwater?

12 minutes

5 times 4 is 20. So multiply 3 by 4. 3 times 4 is 12.  A dolphin would hold its breath for 12 minutes.
