A 330 yard long train, travelling at 50 mph, enters a three mile long tunnel. How long will elapse between the moment the front of the train enters the tunnel and the moment the end of the train clears the tunnel?
Train length=d1=330yard Tunnel length=d2=3miles=3*1760=5280yards Total distance=d=d1+d2=330+5280=5610yards Speed=S=50mph={(50*1760)/3600}yard/sec Time=t=d/s=5610/{(50*1760)/3600}=229.5sec Ans is 229.5 sec
