here is my question: assume you take a car trip and you average 65 mph for the trip. Use the mean value theorem to explain what we can guarantee regarding the reading on your speedometer at least once during the trip.

Best ResponseYou've already chosen the best response.0"At least once the speed will have been 65mph". As speed is a continous thing, (one can't just go from 50mph to 70mph), you would have thus passed through 65 at least once.

Best ResponseYou've already chosen the best response.0(it should also be noted that speed is the derivative of position, and thus subject to the MVTs rules)

Best ResponseYou've already chosen the best response.0In order to show work for this would this be correct: f'(65)=[f(b)f(a)]/ba a<65<b

Best ResponseYou've already chosen the best response.0well, a and b are partiular times, f(b), f(a) is position, and f'(c) is your speed at a particular time c. I'm not fully sure how one would show work for this without given specific values  my apologies.

Best ResponseYou've already chosen the best response.0But saying a<65<b is meaningless. I mean, you can pick times for both a and b so that the statement is true, but it shows nothing.
