Explanation:

Step1: Identify the time intervals

The horizontal line segments represent periods of rest (in the bank).

Step2: Calculate the time in the bank

The first horizontal segment is from \(x = 1\) to \(x = 8\) (time in bank \(=8 - 1=7\) minutes). The second horizontal segment is from \(x = 14\) to \(x = 17\) (time in bank \(=17 - 14 = 3\) minutes).

Step3: Sum the time intervals

Total time in bank \(=7+3 = 10\) minutes.
