During a 10-week summer vacation, was the average (arithmetic mean) number of books that Carolyn read per week greater than the average number of books that Jacob read per week?

(1)Twice the average number of books that Carolyn read per week was greater than 5 less than twice the average number of books that Jacob read per week.

(2)During the last 5 weeks of the vacation, Carolyn read a total of 3 books more than Jacob.

话说这个（1）是神马意思呢？如果average C是X，average J是Y。是说2X>2Y-5吗？？
