The path of a total solar eclipse is modeled by f(t)=0.00388t^2 - 0.493t + 43.363, where​ f(t) is the latitude in degrees south of the equator at t minutes after the start of the total eclipse. What is the latitude closest to the​ equator, in​ degrees, at which the total eclipse will be visible.

The latitude closest to the equator at which the total eclipse will be visible is ____ S

​(Round the final answer to two decimal places as needed. Round all intermediate values to four decimal places as​ needed.)
