The train travels at 123.7 km/h
In 6 hours @ 120 km per hour, the train travels 120*6 = 720 km. In 5 hours @ 100 km per hour, the train travels 100*5 = 500 km. So, in all the train travels 720 + 500 = 1220 km in 6 + 5 = 11 hours. Its average speed is 1220/11 =110.9090.. recurring km per hour.
The average speed if an airplane travels 1364 miles in 5.5 hours is 248 miles/hr.
Speed = Distance/Time = 100 km / 4 hours = 100/4 km per hour = 25 kph
131.82 miles per hour.
