Answer:
120 minutes
Explanation:
Total plants are 16 and only 5 can be placed in one go. so total number of rounds for the plants will be: 16/5 = 3.2 rounds ≅ 4 rounds
As there are four rounds to go in 8 hours, so the time for 1 round will be: 8/4 = 2 hours.
Therefore, 2 hours or 120 minutes of sunlight are possible for one plant ..
