A softball player was running from first to second base at a speed of 25 ft/s when she was 10 ft from second base. To find the rate of change of her distance from home plate, a right triangle was drawn with the bases as sides and the player's path as the hypotenuse. The rate of change was calculated using the player's speed and the triangle's dimensions.
