Question
A library employee takes 45 seconds to process a returned item. One morning there were 30 items in the book return bin. How long did it take the employee to process all of the returned items? A. 22 ½ minutes B. 30 minutes C. 45 minutes D. 135 minutes E. 1350 minutes
Solution
First, we need to find out the total time it takes to process all the returned items.
We know that it takes 45 seconds to process one item. So, to find out the total time, we multiply the time it takes to process one item by the total number of items.
45 seconds/item * 30 items = 1350 seconds
However, the answer choices are in minutes, not seconds. We know that there are 60 seconds in a minute, so we divide the total time in seconds by 60 to convert it to minutes.
1350 seconds ÷ 60 = 22.5 minutes
So, the correct answer is A. 22 ½ minutes.
