3 hours and 40 minutes = 1/3 job.

Therefore in order to complete a whole job. You multiply both sides by 3.

3 hours 40 minutes * 3 = 1 job

11 hours = 1 job

1 hour = 60 minutes.

3 hours and 40 minutes is a third of a whole job.
A whole job is therefore 3 lots of 3 hours and 40 minutes.

3 hours x 3 = 9 hours

40 minutes x 3 = 120 minutes
120 minutes / 60 minutes = 2 hours.

9 hours + 2 hours = 11 hours.
