Question

A post office functions from 10 a.m to 5.45 p.m with a lunch break of 1 hour. If the post office works for 6 days a week, find the total duration of working hours in a week

Answer 1

Closing time of the post office 5.45 p.m. = (5 + 12):45 hour

= 17:45 hours.

Starting time of the post office = 10 a.m

= 10:00 hours

For a day total working hour without break = 17:45 hour – 10:00 hours

= 07:45 hour

Lunch break = 01:00 hour

Duration of Working hours = 6:45 hours

For 6 days working hours = 6:45 hour × 6

= (6 hours 45 minutes) × 6

= 36 hours 270 minutes

= 36 hours + (4 × 60 + 30) minutes

= 36 hours + (4 hours + 30 minutes)

= 40 hours + 30 minutes

The total duration of working hours in 6 days = 40 hours 30 minutes.
