024 - Ave Caesar

"Are these all of them?" asked Detective Dockland.

"Yes," replied Hillary Black. "I've given you a copy of every other document in the safe on the night of the robbery. I should warn you, though, they're all encrypted."

Dockland glanced briefly at the top document in the stack. "I don't think much of your idea of encryption."

"Oh, that one's not serious encryption. She just does them that way for fun," said Hillary.

Dockland paused, and looked at the document longer, before adding, "She's right, in that the math problem is't very hard either."

What is the answer to the math problem Dockland is referring to? The document reads, in full:

016 - Brevity of Communication

Kent Dockland doesn't get on well with his co-workers at the Serendipity Police Department. Today, as he's trying to finish some incident reports on his computer, he's distracted by his co-workers loudly discussing the comparitive merits of cars, motorcycles, and speedboats.

Peter Bernard, the loudest, meanest cop on the force, spots Kent at his computer. "Hey Kent!" he yells. "What kind of vehicle do YOU like?

"Here's the thing, Peter," says Kent. "This isn't news. You understandably really like cars or motorcycles. But I have to finish this incident report, it's due today, and you and your idiot friends aren't helping."

Peter scowls. "Don't be a loser, Kent. The report can wait five minutes. What's your vehicle of choice?"

Kent stares at Peter, and says, "I just told you."

What is Kent's favourite kind of vehicle?
