How many boxes of candles did a worker pack per minute if they packed 105 cases, each containing 12 boxes, in 1.5 hours?

The correct answer is: 14

To find out how many boxes of candles the worker packed per minute, we first need to calculate the total number of boxes packed and then divide that by the total time taken in minutes. First, determine the total number of boxes. Since there are 105 cases and each case contains 12 boxes, we multiply these two numbers: 105 cases × 12 boxes per case = 1260 boxes Next, we need to convert the packing time from hours to minutes. The worker packed for 1.5 hours, and since each hour has 60 minutes, we calculate the total packing time in minutes: 1.5 hours × 60 minutes per hour = 90 minutes Now, we can calculate the number of boxes packed per minute by dividing the total number of boxes by the total time in minutes: 1260 boxes ÷ 90 minutes = 14 boxes per minute Therefore, the worker packed 14 boxes of candles per minute. This figure aligns with the answer choice indicating that the worker's rate of packing was efficient given the total amount worked in that time frame.
