re: Off-Topic

BTW country, I don't want your post to get lost in all the blather about trivial math problems. This this hits us all in the feels for sure, I know we're all thinking about you guys this evening.

No doubt about it. 100%.

I had the same thought....diabolical bastard. I expect him to drop some serious knowledge on us about this at some point. How long is he going to let us make fools of ourselves?


BTW, I'm deleting all my posts about this topic when the right answer is revealed....

I dont mind being wrong, but if blzr comes back and says there is no answer...

I'm going straight to the mods. Perma-ban!

I hear gears grinding. Are we in the right thread?

re: Off-Topic

Say you're riding a bike on a two-mile path, the first mile being uphill and the second mile downhill. At best, you are only able to ride the first mile uphill at an average speed of 15 MPH. How fast would you have to bike on the downhill mile to achieve an overall average speed of 30 MPH for that two-mile path?

Done.

I am on my Vita right now in the theater about to see Christopher Robin so I can't type forever. Before that I was seeing Mission: Impossible - Fallout again. I wasn't just sitting back and laughing all day, but I am right now.

Below is the closest answer and reasoning though.

Distance = Rate x Time

In order to average 30 MPH over 2 miles, you must cover that 2 miles in 4 minutes.

Spoiler

2 Miles = 30 Miles/Hour x Time
Time = 1/15 Hour = 1/15 x (60 minutes/ 1 Hour) = 4 minutes

If you go 15 MPH over 1 mile, it took you 4 minutes of time (assuming constant rate of speed).

Spoiler

1 Mile = 15 Miles/Hour x Time
Time = 1/15 Hour = 1/15 x (60 minutes/ 1 Hour) = 4 minutes

Ergo....infinity?

I'm not saying my logic is correct. I'm saying that's how I approached the problem.

The logic is correct. You averaging 15 MPH for the first mile would get someone averaging 30 MPH during that same time to complete both miles, so it is impossible to achieve.

I don't quite liken that to "no answer" though. I just wanted to do a problem that requires as much logic as that it does math. If you all want true math questions, I have no problems delivering those as well.

And yes, initially Einstein thought 45 MPH.

EDIT: Just saw your post cb. Hang in there man. I won't let this riddle derail your situation man. I really hope he pulls through this!

Einstein was a fool.

No offense Caulfield. Hey, youre as smart as Einstein!

re: Off-Topic

Now I need to go back and question if 2+2=4. I seem to recall someone else saying its 2X2=4

what is the sound of one fist shaking?

Touche. Strictly speaking, 'infinity' is incorrect. Still hard to wrap my mind around the fact that it's impossible to achieve though...

Kudos to NolanRyansSnowMonkey as well. We're officially half as logical as Blzer's math students!

Can't even handle any more math/logic problems right now. My brain cells need beer to continue...

re: Off-Topic

So.... what would happen if you did go faster than the speed of light and stayed alive for that second mile? How fast would the average speed be then?
I think i know juuuuuust the perfect thread to pose such a question...

re: Off-Topic

What does uphill/downhill have to do with anything if we are talking average mph?
Still wondering about that.

You can ride faster downhill than you can uphill. I was just giving more logic to the situation. I didn't want to include that extra fluff in the problem itself.

< 30 MPH is the best answer that a mathematician can give.

Sorry, I don't know how to edit in a multiquote on Vita.

re: Off-Topic

Blzer’s 99 doors explanation made great sense to me. Reminds me of that boy-girl/boy-boy/girl-girl probability question from a few months back.

You still wouldn't achieve the average of 30 MPH. Based on the math, you have to cover the 2nd mile in 0 seconds (0 time). Anything more and you don't hit a 30MPH average over the 2 miles. You could get agonizingly close, but 29.999 is not equal to 30. Although 29.999 (repeating for infinity) DOES = 30. Sort of. But that's another discussion.

Also of note, the force required to accelerate yourself to light speed approaches infinity, as your mass approaches infinity the closer you get.

But that's at least 2 different threads and no one is interested....
