For a construction project, the mean and standard deviation of the completion time are 200 days and 6.1 days, respectively. Assume normal distribution and use the value of standard normal deviate $z=1.64$ for the $95 \%$ confidence level. The maximum time required (in days) for the completion of the project would be
