The learning rate formula is:

Learning rate = (time for first attempt - time for second attempt) / time for first attempt x 100

Plugging in the numbers we get,

Learning rate = (60 - 48) / 60 x 100
             = 12 / 60 x 100
             = 20%

Therefore, the learning rate for this person is 20% which is closest to option C - 80%.
