Ten small planes are flying at a speed of 150 km h in total darkness in an air space that is 20 x 20 x 1 5 km in volume You are in one of the planes flying at random within this space with no way of knowing where the other planes are On the average about how long a time will elapse between near collision with your plane Assume for this rough computation that a safety region around the plane can be approximated by a sphere of radius 10 m a 125 h b 220 h c 432 h d 225 h
