A car service charges customers a flat fee per ride (which is higher during rush hour traffic) plus charges for each minute and each mile. Suppose that, in a certain metropolitan area during rush hour, the flat fee is $5, the cost per minute is $0.30, and the cost per mile is $1.50. Let x be the number of minutes and y the number of miles. At the end of a ride, the driver said that the passenger owed $14.60 and remarked that the number of minutes was three times the number of miles. Find the number of minutes and the number of miles for this trip.
