How long would it take to fill a 30 yd^3 packer truck that compresses waste to 750 lb/yd^3 if it travels 100 ft between stops at an average of 5mph and it takes 1 minute to load 200 lb of waste at each stop? if each stop services four homes and two collections runs are made per day, how many customers could be provided with once per week service by this single truck(assuming a five-day week)?
