Out of the 50 states, Hawaii has the least number of roadway miles, followed by Delaware. If Delaware has 1585 more roadway miles than Hawaii and the total number of roadway miles for both states is 10,203, find the number of roadway miles for each state. In a championship basketball game, Paula Zimmerman made twice as many free throws as Maria Kaminsky. If the total number of free throws made by both women was 12, find how many free throws Paula made.
