Explanation:

To convert the passive sentence "This delay was caused by an accident" to active voice in simple past tense, we identify the agent (an accident) as the subject, the action (caused) in simple past, and the original object (this delay) as the object. So the structure becomes: Agent + past tense of verb + object.

Answer:

An accident caused this delay.
