40km per hour
In 1 hour it travels 60 km Hence In 6 hours it travels 6 x 60 = 360 km
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.
Speed of light * * * * * Nothing, since the speed of light in vacuum is around 1080 million km/h. In any case, the "speed of light" does not travel!
Speed is NOT measured in km but km PER HOUR. The average speed was 88.88 (repeating) km per hour.

60 km an hour
Nothing does. That speed is 3.5% greater than the speed of light.
Nothing in the known universe - since the speed of light is 1080 million kilometres per hour !
Well - someone else on here asking the same question, got the answer "the speed of light" - but the speed of light in km/h is 1,072,984,320 Wikipedia gives 1079 million kph, but the answer remains vaid.
40km per hour
29 km per hour.
1 hour 3 minutes.
40 km per hour. 20 x 2 because that is in a half hour.
In 1 hour it travels 60 km Hence In 6 hours it travels 6 x 60 = 360 km
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.
