A wholesaler has divided a delivery of firm, unripe avocados into two batches. Batch 1 will be sent to supermarkets in 3 days. Batch 2 will be sent to supermarkets in 10 days. Both batches must arrive ripe and ready for sale.
The wholesaler must choose one of these treatments to start now for each batch:
The treatment of Batch 1 cannot be changed before it is sent. The treatment of Batch 2 can be changed shortly before it is sent, when ethene will be added.
State the treatment that should be started now for each batch.
| Batch | Treatment to start now |
|---|---|
| 1 | |
| 2 |
A supermarket wants the avocados to be ripe for a promotion on a particular date.
Explain how controlling the ethene treatment helps the wholesaler meet this requirement.
