What's the acceleration if the average velocity is 3.5 and the time is 8.7

A closed system consisting of 2 lb of a gas undergoes a process during which the relation between pressure and volume is pVn = constant. The process begins with p1 = 15 lbf/in. 2, ν1 = 1.25 ft3/lb and ends with p2 = 60 lbf/in. 2, ν2 = 0.5 ft3/lb.
