Consider the following "transportation system,"
• A one-mile stretch of single-lane highway between two mile markers (1 mile = 5280 feet)
• Cars traveling in the same direction at the speed of 30 miles per hour and keeping the same distance between them as specified below.
• Assume that the front bumper of a car represents the car. Thus, when the front bumper of a car reaches a mile marker, we assume that the car has reached the mile marker. The average distance between the front bumper of one car to the front bumper of the car immediately behind it is 60 feet.

Answer the next four questions using the above description of the transportation system.

1. What is the cycle time (in minutes) for a car going through the system?

2. Assuming a steady flow of cars entering the system, what is the average takt time (in seconds/car)?

3. Changing only one assumption about the system, that it is a two-lane highway, what is the cycle time for a car? Changing only one assumption about the system, that it is a two-lane highway, what is the average takt time?

4. Changing only one assumption about the system, that it is a two-lane highway, what is the average takt time?
