We want to know how long they will take to actually get the FULL job done.
Step 1: Turn them into fractions. We need to convert the amount of time “A” takes and “B” takes to the simplest form possible. “A” will complete 1/20 of the job in one minute. “B” will complete 1/30 of the job in a minute.
Step 2: Adding the fractions. Now, we add 1/20 and 1/30 together. 1/20 plus 1/30 is equal to 3/60 plus 2/60 which gives us the answer of 5/60. If the pay work together, they will accomplish 5/60 of the job in a minute. Now, this is ONLY 5/60. We want to know the amount of time they take to get the FULL job done.
Step 3. Divide 60 by 5. Sixty divided by five is equal to 12.
As a result, team “A” and team “B” take 12 minutes to get the job done if they work together.
ANSWER : 12 MINUTES.
