A freight train travels from City A to City D with three legs: A‑B (120 km), B‑C (80 km) and C‑D (150 km). It runs at \(80\) km/h on the first leg, but on the second leg its speed is reduced by \(10\%\) because of a gradient. After reaching C it must stop for a mandatory inspection lasting \(45\) minutes, then proceeds at \(90\) km/h on the final leg. There is a \(5\%\) chance of an additional delay of \(30\) minutes on the B‑C leg, independent of other events. Calculate the expected total journey time in hours, rounded to two decimal places.
