Develop an optimized cost estimate to move the 17,080 bcy a distance of 12 stations using push-loaded Cat 637K scrapers. Calculate the dozers cycle time (assume a 200-ft, one-way push at an average speed of 2.5 mph) to decide whether the scrapers or the dozer controls the production rate. Use an average speed of 15 mph for the scrapers if they control the production rate and 12 mph if the dozer controls the rate. Indicate the total cost ($) and the unit cost ($/bcy).
