A study of king penguins looked for a relationship between how deep the penguins dive in meters xx to seek food and how long they stay underwater in minutes yy. Based on sample data, the regression line is found to be \hat{y} = 2.69 +0.0238x Use the regression line to estimate how long a typical dive of 200 meters would last. Round your answer to two decimal points.
