This is way off the topic of preterism, or even the Bible. But it does have to do with our "figurer," the brain, and how it analyzes and logically comes to certain conclusions...
Here is a question which I hope everyone will attempt to answer...
A man, beginning at point "A," drives to point "B" averaging 30 mph. The distance between point "A" and point "B" is exactly one mile. He continues driving to point "C" with the intention of averaging 60 mph for the entire A to C trip. The distance from point "B" to "C" is also exactly one mile.
So, how fast must he average from Point "B" to point "C" (one mile) in order to average 60 mph for the entire two-mile trip (A-C)?
Is it:
a) 90 mph
b) 100 mph
c) 120 mph
d) 150 mph
e) some other speed
f) and if e), then what speed?
Hope you will it a fruitful distraction...

I love logic problems, but not crazy about it when they include math. My initial thought is 90 mph. But I'm sure I should put some more effort into calculating it to see if that is correct.

I say "e" because you said that he continues on from point B to point C. His average from B to C is 60. But if you had stated that it was going to be a continuous trip from A to C then with an avg. between A and B would be 30 and B to C would be 60 but the over all avg. would be 45 (I think?) |

It's impossible. In order to average 60 mph over 2 miles, you'd have to complete the whole trip in two minutes, but the driver has already used up 2 minutes in the first mile.
Maybe?

Allyn, I did not say his average speed from B to C was 60... He averaged 30 mph for A to B... How fast must he average in the B to C trip in order to average 60 mph for the entire two mile trip A to C? |

PaulT's answer from CARM concerning this question was: " This coming from a guy who advocates grand conspiracy theories were behind the translation of all the English Bibles. LOL," Need we say more of how this fellow really needs to be completely ignored. |

Bev, Speed Limit 186,000 miles per sec. It's the Law. It's impossible. In order to average 60 mph over 2 miles, you'd have to complete the whole trip in two minutes, but the driver has already used up 2 minutes in the first mile. Maybe? |

Is it: a) 90 mph b) 100 mph c) 120 mph d) 150 mph e) some other speed f) and if e), then what speed? Hope you will it a fruitful distraction... I'll say (e) From point A-B, averaging 30 mph it would take exactly two minutes to drive 1 mile. From point B-C, which is the same distance as A-B, 1 mile, he now wants to make the entire trip, point A-C in the same amount of time as if he were traveling 60 mph. The man would need to be Hans Solo, and he would have his buddy, Chewbacca waiting for him at the end of his first drive, point A-B. Hans would get out of his Ford Falcon, kiss Princess Leia, shoot a few storm troopers, climb into the Millennium Falcon, say something funny to Chewy, punch the Falcon into light speed, which would be going 186,000 miles per second. Since Hans had R2D2 working on the Falcon(Millennium that is) , it would now be going twice that speed, which is 372,000 miles per second, taking him back in time. Since the kiss from Princess Leia was a long one, (at least 20 seconds) and the fight with the storm troopers took over a minute, and at least 1 minute for Hans to get up into the Millennium Falcon and buckle up, he was truly in need of some serious petal to the titanium to make up 2 minutes and 20 seconds, plus meet his goal of averaging 60 mph from A-C., hence R2D2's magic mechanical touch. Blowing by 5 Corellian corvette's sent out from a Naboo royal starship to thwart this successful mission, Hans went back into time exactly 4 minutes and 20 seconds. Chewy dropped him back off at the Falcon (Ford, that is) at the exact time he left when he started on this experiment going from point A-B. Hans kissed Leia again and got in (2 minutes total from leaving the Millinium Falcon, kissing, and getting into the Ford Falcon) popped a Coke and drained it (20 seconds), Hans proceeded to drive the last mile going 60 miles per hour, thereby averaging 60 mph exactly from point A-C, for a total of 2 miles in 2 minutes, going 372,000 miles per second.  |

Bravo, Steve! You win the medal for creative writing!

To travel at an average of 60 mph is 1 mile per min. Since he already took 2 minutes to drive the 1st mile at 30 mph, he cannot recover his time by driving faster because the time is already spent.
oops I see Bev came up with the same...

That was cool, but you lost me somewhere after the 20 second kiss.  |
