Final answer:
It would take approximately 29,217.6 minutes, or around 486.96 hours, for a window washing crew to wash 24,348 windows, working at their established rate non-stop. This equates to approximately 0.055 years.
Step-by-step explanation:
To determine how long it would take for a window washing crew to wash 24,348 windows, we first establish their rate of washing based on the information that they can finish 15 windows in 18 minutes. This tells us that the crew can wash one window in 18/15 minutes or 1.2 minutes per window. By multiplying the time it takes to wash one window with the total number of windows, we can calculate the total amount of time needed.
- Calculate the time to wash one window: 18 minutes ÷ 15 windows = 1.2 minutes per window.
- Multiply this by the total number of windows: 1.2 minutes/window × 24,348 windows = 29,217.6 minutes.
- Convert minutes to hours: 29,217.6 minutes ÷ 60 minutes/hour = 486.96 hours.
- Convert hours to years (assuming a non-stop operation): 486.96 hours ÷ 24 hours/day ÷ 365 days/year = approximately 0.055 years.
In summary, it would take approximately 0.055 years for the crew to wash 24,348 windows assuming they work non-stop without breaks.
