Step-by-step explanation:
Rick and Debbie are painting a large barn. Debbie paints twice as fast as Rick. They work together for 16 hours and complete the job. Determine how fast Debbie and Rick can paint the entire barn separately.
= 1/a + 1/2a = 1/16
= 2a + a/2a² = 1/16
2a/2a² = 1/16
= 1/a = 1/16
