To find out how long it will take Ciarra and Luisa to edit the reports together, we can follow these steps:
1. Calculate the individual rates of work for Ciarra and Luisa:
- Ciarra can edit 15 reports in 10 hours, so her rate is 15 reports / 10 hours = 1.5 reports per hour.
- Luisa can edit the same number of reports in 15 hours, so her rate is 15 reports / 15 hours = 1 report per hour.
2. Find the combined rate of Ciarra and Luisa working together:
- When they work together, their rates of work are additive, so Ciarra's rate + Luisa's rate = 1.5 reports per hour + 1 report per hour = 2.5 reports per hour.
3. Determine the time it will take them to edit the reports together:
- To edit a total of 15 reports at a combined rate of 2.5 reports per hour, they will take 15 reports / 2.5 reports per hour = 6 hours.
Therefore, Ciarra and Luisa will take 6 hours to edit the reports together.
