A = P*(1+r*t)
1350 = 1200*(1+0.022*t)
1+0.022*t = 1350/1200
1+0.022*t = 1.125
0.022*t = 1.125-1
0.022*t = 0.125
t = 0.125/0.022
t = 5.681818181818... where the "18" repeats forever.
It takes about 5.6818 years depending how you round this decimal value.
If rounding to the nearest whole year, then it would be 6 years.

Extra info:
5.6818 years = 5 years + 0.6818 years
5.6818 years = 5 years + (0.6818*12) months
5.6818 years = 5 years + 8.1816 months
