My roommate agreed with you on all but the last one he said "equal to" if that's an option. He says he's certain! I dunno he's a math guy so

Well he's going at it again on paper this time. Was equal to an option at all? Also is this a limited guess kind of thing?

Also, idk if this is a limited guess thing. Its use of both the dopler effect formulas, the one for receding and approaching sources

Ok the second is greater than and the final equal to. He didn't take the time to check his work on it last time. But I dunno he I tried to get him to double check the other parts but he felt certain of them.

His reasoning for the Equal to part is that "when the car is far away, the component of its velocity directed toward the guy is approximately equal to its speed". But man I'd only go with this if you get unlimited guesses

He muttered "No problem" and then shut his door, most likely retiring to his manga for the evening.
