Final answer:
The question requires examining a matrix to determine the driving time from friend X to friend Y; however, the matrix was not provided in the question. Without the matrix, it is impossible to give a specific answer.
Step-by-step explanation:
The student has presented a scenario involving a matrix that represents the number of minutes four friends spend driving to each other's homes. To determine how many minutes friend X spends driving to friend Y's home, we would need to look at the appropriate cell in the given matrix. Unfortunately, the matrix is not provided in the question itself. As a result, we cannot provide a numeric answer to the student's question. If the student can provide the matrix, we would locate the row associated with friend X and the column associated with friend Y and read off the value where the row and column intersect, which would give us the driving time.
