Calculating the Total Area Painted by the Painter and the Apprentice
To calculate the total area that the painter and the apprentice can paint together in 8 hours, we can use the following approach:
1. Calculate the individual rates of painting per hour for the painter and the apprentice. 2. Use the rates to determine the total area they can paint together in 8 hours.
Let's proceed with the calculations.
Individual Rates of Painting per Hour
The painter can paint 24 m² of walls in 6 hours, and the apprentice can paint 18 m² of walls in 6 hours. To find their individual rates of painting per hour, we can use the following formulas:
- Painter's rate = Total area painted by the painter / Time taken by the painter - Apprentice's rate = Total area painted by the apprentice / Time taken by the apprentice
Using the given information, we can calculate their individual rates of painting per hour.
Painter's rate: 24 m² / 6 hours = 4 m²/hour
Apprentice's rate: 18 m² / 6 hours = 3 m²/hour
Total Area Painted Together in 8 Hours
To find the total area they can paint together in 8 hours, we can add their individual rates of painting per hour and then multiply the sum by 8 hours.
Total area painted together: (4 m²/hour + 3 m²/hour) * 8 hours = 56 m²
Therefore, working together for 8 hours, the painter and the apprentice can paint 56 m² of walls.
I hope this helps! If you have any further questions, feel free to ask.
