1. The problem asks to add up final answers and express the sum in the format w:d:h:m:s (weeks:days:hours:minutes:seconds). 2. Since no specific numbers are given, let's assume we have final answers in seconds to add. 3. Suppose the total sum in seconds is $T$. 4. Convert $T$ seconds into weeks, days, hours, minutes, and seconds using the following conversions: - 1 week = 604800 seconds - 1 day = 86400 seconds - 1 hour = 3600 seconds - 1 minute = 60 seconds 5. Calculate each unit: $$w = \left\lfloor \frac{T}{604800} \right\rfloor$$ $$T = T - w \times 604800$$ $$d = \left\lfloor \frac{T}{86400} \right\rfloor$$ $$T = T - d \times 86400$$ $$h = \left\lfloor \frac{T}{3600} \right\rfloor$$ $$T = T - h \times 3600$$ $$m = \left\lfloor \frac{T}{60} \right\rfloor$$ $$s = T - m \times 60$$ 6. The final answer is expressed as $w:d:h:m:s$. Since no specific values were provided, this is the general method to convert a total number of seconds into the desired format.
