The sea cow can stay under water for 16 minutes.
Step-by-step explanation:
A hippopotamus can stay under water for 15 minutes.
A sea cow can stay under water
minutes and this is 11 minutes longer than one-third the time a hippopotamus can.
So, "11 minutes longer than one-third the time a hippopotamus can" means:![[\frac{1}{3}(15)+11] minutes](/tpl/images/0030/3566/6b8f3.png)
