OK – I came up with this one many many years ago, and just this past year finally came up with the correct answer. I asked my best friend, who happens to be a math teacher, and he had some ‘crazy math answer’, but not a true number. See if you can come up with a real time… Its one of those ‘a car is driving from point A to B type questions’

A car is sitting at point A at a dead stop. DO NOT account for: 1. Friction 2. Wind speed or 3. The effort to gain speed. Point B is exactly 60 miles away. For the first mile the car goes exactly 60 miles an hour. As its front wheels cross the next mile marker from, its speed automatically (instantaneously) drops to 59 miles an hour. The car continues to drop its speed, matching the number of miles left, until on the last mile the car drives 1 mile an hour. At point B, when the front wheels cross the ‘finish’ line, the car comes to an immediate halt.

How long would it take to drive the 60 miles?

Hint: The first mile takes a minute; 60 MPH for 1 Mile (you can cover 60 miles in one hour, and there are 60 minutes in an hour, so 1 Mile (1/60th of the time) is 1 Minute))
The last mile will take an hour to drive, obviously, 1MPH and driving 1 Mile means it will take an hour.

Round off - Hours / Minutes / Seconds, no tenths of a second or anything ;)

S.W.A.G....... 30 hrs and 30 minutes

S.W.A.G....... 30 hrs and 30 minutes
I agree

4.67987 hours

Scott is dead-on.

Scott, 5 hours / 8 minutes / 38 seconds? The 67 minutes would make it 5 hours and 7 minutes, the 98 seconds would make it 5H / 8M / 38S. My head hurts from the airplane/treadmill - but Im pretty sure thats correct. Using a calculator for time makes my head spin, cause there's no such thing as 99 seconds, so getting it to roll over to 1 minute and 39 seconds takes some hand jamming.
Forget this, Im going to the garage lol. Im pretty sure your correct, I came up with the same thing.

ummm, long time?

ouch! that gave me a head ache! please dont do that again...

Scott........ :thumbsup:

If you say so.

Scott is right.


it would take 280.7922 minutes ... divided by 60 (convert to hours) ... would be 4.679870413 hours ... take 60 minutes (1 hour) and times by the .679870413 would equal 40.79222478 minutes ... take 60 seconds (1 minute) and times by the .79222478 would equal 47.53348663 seconds .... so:

4 hours, 40 minutes, ~47.5 seconds.
