Challenge Problems
Push your limits with advanced challenges
A construction site requires 15 cubic meters of gravel to be moved every hour. Each truck can hold 7.5 cubic meters, and the loader operates at 2 minutes per load. Determine the number of trucks required to meet this demand, ensuring they operate within safety limits for gravimetric capacity.
💡 Hint: Use the demand and truck capacity to derive the required number of trips.
A truck is loaded with sand having a density of 120 lbs/ft³. If the truck's gravimetric capacity is 10,000 lbs, calculate the maximum volume of sand that can be loaded.
💡 Hint: Think about how to express the relationship between weight and volume!
