A drone operator is on a road running north and south, and using a drone to observe a herd of caribou 4900 yards east and 500 yards north of the operator's position. If the drone flies so that the distance from the road is three times to the distance to the herd, describe the path of the drone, then determine how far will it be from the drone operator when it crosses an east-west line through the operator's position. The path of the drone has the shape of a point parabola O straight line ellipse hyperbola When the drone crosses the east-west line through the operator's position, it will be yards from the operator (enter your answer rounded to the nearest whole number; if there is more than one answer, enter both, separated by commas)
