Calculate the productivity of a bulldozer that completes a cycle in 30 minutes with a blade load of 100 cubic meters. If job efficiency is 75%, what is the effective productivity?
💡 Hint: Remember to convert minutes to hours when calculating.
Given that the bulldozer operates under poor visibility and an experienced operator takes longer, adjust the productivity estimate by applying a correction factor of 0.85. If initial productivity was 180 cubic meters per hour, what is the adjusted productivity?
💡 Hint: Use the formula for adjusting productivity based on the factors discussed.
