The learning curve of 90% means that each time the production quantity doubles, the time taken to produce each unit falls to 90% of the previous unit's time. Therefore, if the second unit took 9 hours, the first unit would have taken longer because there was no previous experience to reduce the time taken. To find the time for the first unit, you divide the time for the second unit by the learning rate (90% or 0.9). So, 9 hours / 0.9 = 10 hours.
