The 5 workers do the job in 1hour and 19 minutes and 48 seconds

The time that it will take workers to do half of the job is; 4 hours 41 minutes 15 seconds

  • We are told that;

15 workers did the job in 8 hours.

  • Thus;

Rate of 1 worker per hour = 15/8 portion per hour

  • For 5 workers to do ½ the job, it means that the time is;

5 × 15/8 × ½ = 75/16 hours

Converting this to hours and minutes gives;

4 hours 41 minutes 15 seconds
