Answer 2

Task Analysis

The task states that a team of 18 loaders is unloading a steamship. They worked for 4 hours before lunch, with each loader unloading 15 boxes per hour. After lunch, the number of loaders doubled. The question is whether they will be able to completely unload the steamship in the remaining 4 hours of work if their productivity remains the same.

Solution

To solve this problem, we need to calculate the total number of boxes unloaded before lunch and after lunch, and then compare it to the total number of boxes that need to be unloaded.

1. Before lunch: - Number of loaders: 18 - Hours worked: 4 - Boxes unloaded per hour per loader: 15 - Total boxes unloaded before lunch: 18 loaders * 4 hours * 15 boxes/hour = 1080 boxes

2. After lunch: - Number of loaders: 18 * 2 = 36 - Hours worked: 4 - Boxes unloaded per hour per loader: 15 (assuming the productivity remains the same) - Total boxes unloaded after lunch: 36 loaders * 4 hours * 15 boxes/hour = 2160 boxes

3. Total boxes unloaded: 1080 boxes + 2160 boxes = 3240 boxes

Since the total number of boxes unloaded is 3240, we need to compare it to the total number of boxes that need to be unloaded in order to determine if they will be able to finish the job.

Unfortunately, the problem does not provide the total number of boxes that need to be unloaded, so we cannot determine if they will be able to finish the job in the remaining 4 hours of work.

Reformulated Problem

To solve the problem, we need to know the total number of boxes that need to be unloaded from the steamship. Please provide this information so that we can determine if the team of loaders will be able to finish the job in the remaining 4 hours of work.
