Beverages can be chilled more quickly using styrofoam boxes containing ice and a little commercial coarse salt. In this process, the ice melts with consequent formation of liquid and cooling of the beverages. An erroneous interpretation, based on common sense, relates this effect to the great ability of coarse salt to remove heat from the ice. From a scientific point of view, rapid cooling occurs due to more efficient heat transfer between the ice, salt, and beverages.

An airplane initially flies north at a speed of 200 km/h. Due to a wind blowing from east to west, the airplane ends up deviating to the northeast, following a trajectory that forms a 45-degree angle with the north direction and covering a distance of 300 km from the starting point. Determine, using vector concepts, the speed of the airplane relative to the ground, considering the effect of the wind. Consider that the wind speed is constant and equal to 50 km/h, and that the wind direction is perpendicular to the initial direction of the airplane.
