The learning-adjusted time estimate for unit number 25 is 0.4665 minute. This is calculated by multiplying the first timing by the unit improvement factor raised to the power of (n-1), where n is the unit number. In this case, the first timing is 5 minutes, the unit improvement factor is 0.0933, and the unit number is 25. So, the learning-adjusted time estimate is 5 * 0.0933^(25-1) = 0.4665 minute.
