Trains on the Glasgow Subway depart every 4 minutes, and a complete circuit takes 24 minutes. Ewan sets off at 8.30 am on a trai
n round in one direction at the same time as another train leaves in the opposite direction. How many trains will he pass on a complete circuit back to his starting station? Do not count trains at the start or end station.
Trains depart after every 4 minutes. Total time train takes to complete a circuit= 24 minutes Evan sets off at 8:30 am, so he will be back at 8:54 am. So time of trains coming in opposite direction: 8: 34 am 8:38 am 8:42 am 8:46 am and 8:50 am 5 trains coming in opposite directions. Now the trains started at 8:06 am from the stations are: 8:06 am 8:10 am 8:14 am 8:18 am 8:22 am and 8:26 am. So there are 6 trains started the circuit at 8:06 am.
