Problem Of The Week - Tunnel Vision

                                              



What I Know- 

*The train is 1000 metres long
*the tunnel is 3000 metres long


Since we have to find the speed of the tran in kilometres per hour we need to convert it, so 1000 metres makes 1km.  So to find the speed for the train per hour you need to divide 1km by an hour = 60mins


   1km
________       =    16.6666666667 is the speed per hour

1hr/60mins
