James walks 1/5 of a mile in 6 minutes. if he continues walking at the same rate, how many miles will he cover in 60 minutes?

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
