A project consists of replacing the track on an existing railroad line, involving 3,000 feet of track. The old track can be removed at a rate of 70 feet per hour. The old railroad ties can be removed at a rate of 200 feet (measured along the track) per hour. The new ties can be installed at a rate of 25 feet per hour, and the replacement track can be installed at a rate of 40 feet per hour. Show this operation on a linear schedule. Assume that the minimum float (buffer) for an activity at any location is 1 day.
