Physicians often estimate the adult height \(c,\) in inches, of a female child by using the inequalities

\(\dfrac{m+f−13.2}2\le c \le \dfrac{m+f−2.8}2,\)

where \(m\) represents the mother's adult height and \(f\) represents the father's adult height, both measured in inches. If Rachel is a 5-year-old girl, what is her maximum adult height that will satisfy these inequalities?

(1) Rachel's height at age 5 is 44 inches
(2) Rachel's mother's adult height is 62 inches and Rachel's father's adult height is 71 inches
