Nancy pose la question : Two trains, each of 80 cars, must pass on a single track which has a deadend siding. How can they pass if the siding can only hold a locomotive and 40 cars?
I do not understand this...help. It will be due monday. I thought it would be simple if the siding could hold 80 cars.
