A man standing on a railway platform noticed that a train took 21s to cross the platform (this means the time elapsed from the moment the engine enters the platform till the last compartment leaves the platform) which is 88m long, and that it took 9s to pass him. Assuming that the train was moving with uniform speed, what is the length of the train in meters?
