2. Solid waste from a new industrial part is to be collected in a large container, so of which will be used in conjunction with stationery compactors. Based on traffic studies at similar parts, it is estimated that the average time to drive from the garage to the first stationary location(t,) and from the last stationary location(t) to the garage each day will be 15 & 20 minute. If the average time required to drive the containers is 6 minute & the one-way distance to the disposal site is 20 mile (speed limit 55mile/hr). Determine the number of container that can be emptied per day based on an 8hr workday. Assume the off route factor W equal to 0.20
