Solving work rate problems
Master Solving work rate problems in Grade 9 Algebra 1. To find the time it takes for multiple people to complete a job together, use the formula: , where is hours worked together.
Key Concepts
Property To find the time it takes for multiple people to complete a job together, use the formula: $(\text{Rate} 1)h + (\text{Rate} 2)h = 1$, where $h$ is hours worked together. Explanation Teamwork makes the dream work, and math can prove it! This formula combines individual work rates (like 'jobs per hour') to find their super powered team rate. Each person's fractional work adds up to one completed job. It's all about how much each person accomplishes per hour. Examples Maria paints a fence in 3 hours $(\frac{1}{3}$ of the job per hour). Leo paints it in 4 hours $(\frac{1}{4}$ of the job per hour). Together: $(\frac{1}{3})h + (\frac{1}{4})h = 1$, so $h = \frac{12}{7}$ hours.
