1. Capacity of shed is 65,000 tonnes. The capacity of production is 100 tonnes/hour, working 24 hours a day, 5 days a week. Therefore, raw sugar is enough for:
= 65,000 / (100*24*5) = 5.4 weeks.
Assuming that a full ship arrives when the shed is half full and just before the St. Lawrence Seaway freeze, there may be enough raw sugar for 2 months, which is not enough.
