Final answer:
The correct way to complete the sentence is with the future simple tense, resulting in 'If we meet at 9:30, we will have plenty of time.'
Step-by-step explanation:
The sentence should be completed with the future simple tense - 'will have' - to indicate a future event that is certain if the condition 'we meet at 9:30' is met. Therefore, the completed sentence reads: 'If we meet at 9:30, we will have plenty of time.'
If we meet at 9:30, we will have plenty of time.
This sentence is in the future tense, indicating that something will happen in the future if a specific condition is met. In this case, the condition is meeting at 9:30. The verb 'will have' is used to express that there will be plenty of time.
For example, if two friends decide to meet at 9:30 AM, they can be confident that they will have enough time to complete their planned activities.
