    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.

    rate of hose 1 =A y=A*8=8A aret of hose 2= B y=B*12=12B y=(A+B)t solve of t : time

    8A=(A+B)t 12B=(A+B)t
