A hospital is located 3 mi west and 4 mi north of the center of town. Suppose that a Medi-Vac helicopter flies at a constant speed from the hospital to the location of an accident 15 mi east and 20 mi south of the center of town in 15 min 1 4 hr . Choose a coordinate system with the origin at the center of town. a. Write parametric equations to represent the path of the helicopter as a function of the time t (in hr) after the helicopter leaves the hospital. b. Where is the helicopter located 10 min after leaving the hospital?

System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.
