Assuming simple interest

I = P*r*t

864 = 9600*0.08*t

864 = 768*t

864/768 = t

1.125 = t

t = 1.125

It will take 1.125 years

1.125 yrs = 1 + 0.125 = 1 + 12*0.125 = 1 + 1.5 = 1 year, 1.5 months

Put another, way, it will take 1 year & 1.5 months. You'll most likely have to round up to the nearest month.
