A hippopotamus can stay under water for 15 minutes. A sea cow can stay under water y minutes. This is 11 minutes longer than one third the time a hippopotamus can. Write an equation and solve to determine how long the sea cow can stay under water.

Y = (1/3)15 +11 =

To solve this problem, let's first set up an equation based on the given information.

Let's assume the time a hippopotamus can stay underwater is "x" minutes.

According to the given information, a sea cow can stay underwater for 11 minutes longer than one third the time a hippopotamus can. So, the equation can be written as:

y = (1/3)x + 11

Here, "y" represents the time a sea cow can stay underwater.

To solve for y, we will substitute the value of x and then solve the equation.

Since we know that a hippopotamus can stay underwater for 15 minutes, we substitute x with 15:

y = (1/3)(15) + 11

Simplifying the equation:

y = 5 + 11

y = 16

Therefore, the sea cow can stay underwater for 16 minutes.
