Show answer & explanation
Correct answer: C
Net active time over a period equals the sum of each day's gross duration minus the total break time deducted across those days: Net time = sum of daily gross durations minus sum of daily break deductions.
Monday to Friday: 9:15 AM to 5:15 PM is a gross duration of 8 hours each day; over 5 days this totals 5 × 8 = 40 hours.
Saturday: 9:00 AM to 12:00 Noon is a gross duration of 3 hours.
Total gross walking time for the week = 40 hours + 3 hours = 43 hours.
Total lunch deduction = 45 minutes per day × 6 days (Monday to Saturday) = 270 minutes = 4 hours 30 minutes.
Net walking time for the week = 43 hours − 4 hours 30 minutes = 38 hours 30 minutes.
Cross-check in minutes: 43 hours = 2580 minutes; 2580 minutes − 270 minutes (total lunch) = 2310 minutes = 38 hours 30 minutes — consistent with the option value above.
