Explanation:

Step1: Calculate total time for 6 patients

Each patient - visit is 45 minutes. For 6 patients, the total time is $45\times6 = 270$ minutes.

Step2: Convert total minutes to hours

Since 1 hour = 60 minutes, $270\div60= 4.5$ hours.

Step3: Add start - time and total time

The hygienist starts at 0800. Adding 4.5 hours to 0800, 0800 + 4 hours = 1200, and then adding 30 more minutes gives 1230.

B. 1230
