Mark can clean his father's office in 30 minutes. His younger sister Lynn can clean the office in 40 minutes. How long will it t
xz_007 [3.2K]
There is a formula for this
Time = [Worker 1 * Worker 2] / [Worker 1 + Worker 2]
Time = 30*40 / (30+40)
Time = 1,200 / 70
Time = <span> <span> <span> 17.1428571429 </span> </span> </span> minutes

Alternate method
In 1 minute, Mark can clean (1/30) of a room
In 1 minute, Lynn can clean (1/40) of a room
Together, they can clean (1/30 + 1/40) = (7 / 120) of a room in 1 minute.
Together, they can clean one room in (120 / 7) minutes.
(120 / 7) =  <span> <span> <span> 17.1428571429 </span> </span> </span> minutes.
