Final answer:
The average time it took Janette to fold and put away each item is 25.6 seconds, calculated by summing the individual times for each item and dividing by the number of items.
Step-by-step explanation:
To find the average time it took Janette to fold and put away all four items, we need to add the times for each item and then divide by the total number of items. The formula for calculating the average is:
Average time = (Total time for all items) / (Number of items)
Let's add up the times:
26.1 seconds (shirt) + 24.3 seconds (sweater) + 33.8 seconds (pants) + 18.2 seconds (scarf) = 102.4 seconds in total.
Now, we divide by the number of items, which is 4:
Average time = 102.4 seconds / 4 items = 25.6 seconds per item.
Therefore, on average, it took Janette 25.6 seconds to fold and put away each item.
