12. Two ships leave a port at the same time and travel in opposite directions. The speed of the faster ship at x km / h is 8 km / h more than that of the slower ship at y km / h. At the end of 2.5 days, the two ships are 4,320 km apart. 1) Find the speed of each of the two ships. 2) Calculate how much longer it would take the slower ship to reach a destination 1,780 km away than the faster ship if they leave the port at the same time. (Give your answer in hours and minutes.)
