How long does it take to move 25 tons of rock with a wheelbarrow?

The time it takes to move 25 tons of rock with a wheelbarrow depends on several factors, including the wheelbarrow's capacity, the distance to be covered, and the worker's pace. Assuming a standard wheelbarrow can carry about 0.1 tons (or 100 kg) per load, it would take approximately 250 trips to move 25 tons. If a worker can make one trip in about 10 minutes, it could take roughly 2,500 minutes, or about 41.7 hours, not accounting for breaks or fatigue. Overall, this task would likely take several days to complete.


Is it wise for a firm to employ a worker at 20 per hour when another worker does the same job for 10 per hour?

It may not be wise for a firm to employ a worker at $20 per hour when another worker can perform the same job for $10 per hour, as this creates unnecessary labor costs. However, factors such as the experience, qualifications, or productivity of the higher-paid worker may justify the wage difference. Additionally, if the $20 worker brings unique skills or contributes to higher overall efficiency, the investment might be worthwhile. Ultimately, the firm's decision should consider both cost-effectiveness and the value each worker brings to the organization.
