Tabitha Works At A Rate Of 1 Unit Every 10 Hours. Working Together With A Coworker, It Only Takes 5.24 Hours To Make 1 Unit. Which Of The Following Models Is a rational equation that could determine the rate at which the coworker produces units?

Answer 1

Let's assume the rate at which the coworker produces units is r units per hour.
According to the given information, Tabitha can produce 1 unit every 10 hours, so her rate is 1/10 units per hour.
When working together, Tabitha and her coworker can produce 1 unit in 5.24 hours.
Using the formula for working together: 1/10 + r = 1/5.24
To get the rational equation, we can rearrange the equation: r = 1/5.24 - 1/10
Therefore, the rational equation that could determine the rate at which the coworker produces units is r = 1/5.24 - 1/10.
