Latasha can shampoo the carpet on the main floor of a hotel in 3 hours. Tim can shampoo the same carpet in 6 hours. If they work together, how long will I.T take them to shampoo the carpet?
Let n be the amount of time it takes for them to shampoo the carpet together. Then: 1/3+1/6=1/n 2n+n=6 3n=6 n=2 hours to shampoo the carpet together ☺☺☺☺
