The average access time refers to the average time it takes to reach a certain record on the tape, and since we are given the time it takes to reach the last record, we can assume that the average access time would be half of that, as we would expect on average to access a record halfway through the tape. Therefore, the answer is 2.5/2 = 1.25 minutes, which corresponds to choice C.
