If you have seen this before, please refrain from explaining the problem until some folks who haven't seen it before have an opportunity to post their responses. Hopefully, everyone gets it right!!

You bike 10 miles at 20 miles per hour and 10 miles at 10 miles per hour. What is your average speed?

Well, if you don't stop I come up with 13.3 mph. But wait, there's the DQ, and the A&W, and a donut shop, and a coffee shop, and a bakery. I'm going to be out here all day.

Hi,

10 miles at 20 MPH = 30 minutes
10 miles at 10 MPH = 60 minutes
30 min + 60 min = 90 min = 1.5 hours
20 miles / 1.5 hours = 13.33 MPH

Unless my analysis is faulty, steve0257 wins. :)

Some advertisement was over the part where you asked what is your ? If asking for average speed, I get 13.3333333333333333333333333333333333333333333333333333333333333333333333333333333mph. If you want to know how old the rider is, it is 63.:)

No, wrong. The color of the bike is white.

The answer, as always, is my average was 18 mph and I am sticking to it (please don;t revoke my PhD :D )

You rode 20 MPH going to the cafe but could only manage 10 MPH on the way back. The difference is obviously Pi.

Have no idea, I was just to busy enjoying the "SMILES"! ;)

07-22-10, 07:34 PM
Whatever the answer is, I'm sure it is way faster than I went today, even doping my Garmin was no help.

Are those metric hours, or imperial?

20 mph + 10 mph = 30 mph

Where did you guys go to school?

EDIT:

I'm sorry, that is TOTAL speed. For AVERAGE speed:

30 mph / 10 miles = 3 mph

Why you can't make it up on the descent:

You climb the 1 mile hill at 5 mph. Then you go back down 1 mile at 100,000 mph. What's your average speed?

Drag over the line to
highlight the answer---> 9.9995 mph = 2 miles / (.2 hrs +.00001 hrs) <--

This is easy. With all the factors accounted for and calculated properly, my average speed is, um, average.

My average speed is ZERO, the bike is the one that is moving. There, that is my story and I will stick with that.

From average speed to square pi's!

That's more than thread drift - that's bicycling in a gale! :)

An accountant would reply by closing the blinds, locking the door, and ask in a hushed voice, "what do you want your average speed to be?"

Pi at the end of a 30 mile ride, I'll go go for that.

If I do a hefty search, I can find where I posed this same problem about 8 years ago, and before that on USENET bicycle groups.

So, THERE!!!

Besides, this is for 50+'rs, and our answers will likely be more mature.

I ride a MTB so my average is 8. There was a Cheesecake Factory across the street from PF Chang's so I did some serious carbo loading for tomorrow. How fast should I try to ride tomorrow Capt. Dnvr?

10 miles at 20 mph = 30 minutes
10 miles at 10 mph = 60 minutes
tptal time is 90 minutes
total distance is 20 miles
Average speed is 13.333mph
What do I win? anything. I think I am not the first to guess this though.

You win Lance Armstrong's jersey on this year's TdF, the one where he fell off the bike and lost all that time averaging 13.33 mph.

But that will be one of the last Armstrong jerseys of the TdF so it could go for millions on E-Bay! LOL

That's what you get for living so far from civilization. If you Google "Pies are square" you'll find a reference for Gina's in Wilton, Wisconsin along the Elroy - Sparta Trail. I know that's a long way from Northern California, but it'll be worth the ride. Be sure to allow some extra time for the ride home.

07-23-10, 08:05 PM
Retro: I'll have to add that to my list of places to visit when I retire and take up touring semi-full time!

P.S. There ARE some uncivilized people around here (mostly in pickups with wide mirrors).

Remember the problem from jr. high school:
A train leaves New york heading west .....
Another train leaves LA heading east .....
:rolleyes:

If bike A is heading east and bike B is heading west then they will crash somewhere between Kansas City and Denver.

If Bike A is ridden by jppe and Bike B is ridden by DnvrFox, they will crash just outside of Washington, DC
