The average time per batch if 4 are produced is (100 + 70 + 62 + 57) / 4 = 72.25
Therefore the learning rate = square root of 72.25/100 = 0.85 or 85%
I do suggest that you watch my free lectures on learning curves, where this is explained. The lectures are a complete free course for Paper F5 and cover everything needed to be able to pass the exam well.
