The learning curve formula is Tn = T1 * n^(log b / log 2), where Tn is the time required for the nth unit, T1 is the time required for the first unit, n is the unit number, and b is the learning curve percentage in decimal form. For a 70% learning curve (b = 0.70) and the third unit (n = 3), the formula becomes T3 = 20 * 3^(log 0.70 / log 2). This calculation results in approximately 11.4 hours for the third unit.
