Let’s find what is the speed of the train in km per second: Speed = 700/35 = 20 km/sec Now to change from km/sec to m/sec multiply by 1000 Therefore; the speed will be 20*1000=20000 m/sec

Speed = Distance ÷ Time We like to work with metres and seconds, so we will need to convert 700 kilometres (km) into metres. The word kilometres tells us how to do this. Kilo = thousand. So, 700 kilo-metres is 700 thousand-metres or 700,000m. The time is already in seconds, so we can leave that as it is. Speed = Distance ÷ Time Speed = 700,000m ÷ 35s Speed = 20,000m/s (metres per second) This is quite a lot faster than even the fastest Maglev Trains which max out at 167.5m/s.

Average speed is 700000/35 = 20000 m/s Unrealistic as it is approx 58 times the speed of sound !!!
