You have a bulldozer with a theoretical productivity of 120 m³/hr. The job is in a dense clay area at 1800 kg/m³, an average operator, poor visibility, and job efficiency of 45 minutes per hour. Calculate the adjusted productivity.
💡 Hint: List all necessary correction factors you'll need to apply and calculate step by step.
A bulldozer operates at a cost of 1500 rupees per hour and achieves a production rate of 70 bank meter cubes per hour. Determine the cost per meter cube and analyze what factors might influence this calculation positively or negatively.
💡 Hint: Make sure to apply the proper formula to find out the cost and identify any variable factors.
