    Jean and Mark are going to fill a pool with 2 different sized hoses. Jean can fill the pool in 8 hours, while Mark can complete it in 12 hours. Their supervisor thinks that the job will take 10 hours to complete if they work together. Explain each step in solving this equation, and determine if the supervisor is correct or not.

    Find rate of filling for each person Jean fills pool on 8 hrs IN hour she fills 1/8 of the pool Mark fills 1/12 in 1 hour together let them they take x hours so we have 1/8 + 1/12 = 1/x Solve for x

    3x/24x + 2x/24x =24/24x
