Question 4054: A train traveling at 100 kmph overtakes a motorbike traveling at 64 kmph in 40 seconds. What is the length of the train in meters?

You can put this solution on YOUR website!
Let the length of the train be L meters.
Since the time for the train to overtake the motorbike is
L/(100-64) hrs (why?)
Now we have L/(100-64) = 40/3600. (1 hr =3600 sec)
So, L= 40/100 = 0.4 meters
