Question #34de6

Answer 1

"...had waited..."

Explanation:

The first phrase in the sentence implies the passage of time ("finally"), so the verb needs to be past tense. Since you are reporting what happened, you would use the past perfect form of the verb.

If you did something unrelated to the bus after it arrived, then using the past tense is sufficient, e.g. "When the bus finally turned up, I examined it for nearly an hour."
