During the peak hour, 600 vehicles approach each of the four legs of a busy intersection (total 2400 vehicles). Without any traffic signal each vehicle loses 15 seconds due to stopping. A new traffic signal is introduced. Seventy percent of the drivers obey the signal and stop for only 8 seconds, while the remaining thirty percent still stop for 15 seconds. All vehicles, however, incur an additional cycle delay of 2 seconds. Calculate the total time saved (in hours, to two decimal places) during that peak hour compared with the situation without the signal.
