Question 311608: When all of the grocery carts escape from the supermarket, it takes Reginald 12 minutes to round them up and bring them back. Because Norman doesn’t make as much as Reginald, it takes Norman 18 minutes to do the same job. How long would it take them working together to complete the roundup?

Let rounding up the carts be 1 job.
Reginald takes 12 minutes for 1 job.
So he does 1/12 of the job in 1 minute.
..
Norman takes 18 minutes for the same job.
he does 1/18 of the job in 1 minute.
..
Together they do 1/18 +1/12 of the job in 1 minute.
= 2 +3 /36
=5/36 of the job in 1 minute.
so to complete the job they take 36/ 5 minutes.
=7.2 minutes
