Tammy's working alone could clean one and a half area in one hour her partner Melissa's working alone could clean up 1/3 of the area in one hour during the contest when the work together how long will it take them to clean the area

Step-by-step explanation:

The basic principle in this type of problem is that work = rate times time or w = rt Tammy's rate is 1/2 of the job in 1 hour and Melissa's rate is 1/3 of the job in 1 hour. When the two of them work together, they both work the same amount of time which is t hours. Tammy's part of the job + Melissa's part of the job=1 complete job. (1/2) t + (1/3) t = 1Multiply both sides of the equation by the lowest common denominator which is 6 resulting in3t + 2t = 5t = 6 t = 6/5 or 1 and 1/5 hour
