Quizplus · Accepted Answer

The learning rate is 75%, which means that each unit takes 75% of the time of the previous unit. So, the 12th unit should take 75% of the time of the 11th unit, which should take 75% of the time of the 10th unit, and so on. So, the 12th unit should take 75% of the time of the 3rd unit, which is 10 hours. So, the 12th unit should take 75% of 10 hours, which is 7.5 hours.
