A = P*(1+r*t)

1800 = 900*(1+0.06*t)

1800/900 = 1+0.06*t

2 = 1+0.06*t

2-1 = 0.06*t

1 = 0.06*t

0.06t = 1

t = 1/0.06

t = 16.6666666666667


It will take 16.6666666666667 years (16 & 2/3 years) for the $900 amount to double at simple interest.

----------
The amount is not relevant.
The increase is 100%
100/6 = 16 2/3 years.
