Answer:
2772.5 years
Step-by-step explanation:
Using the equation for radioactive decay of material:

Where:
N is the amount of the material at time t,
is the original amount of the material, and k is the rate constant.
The value if the rate constant (k) = 0.693/

Where:
is the half life = 5730 years.
Then k = 0.693/5730 = 0.000121 (1/year)
Then solving for 't', we have:

t = -0.3355/-0.000121 = 2772.5 years
Therefore, the wooden boat is 2772.5 years old.
