Tristan rowed 16 miles downstream in 2 hours. The trip back, however, took him 4 hours. Find the rate that Tristan rows in still water and the rate of the current. Express your answers as integers or rounded to one decimal place.

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
