    Ok. Lets see who can properly answer this question. 2 cars (A and B) leave from
    el paso tx at the same time. Car A goes to las vegas nevada (723 miles away) and car B goes
    to oklahoma city oklahoma (740 miles away). Both cars drive at a rate of 60 miles
    per hour. If they both leave at 4pm, what time would each of them reach their
    destination, and how many hours apart would that place them. (round to the nearest
    half hour)


    Hint: Depending on which way you look at it, there is more than one right answer for
    the last part of the question.

    There are 3 time zones involved. If you allow only 1 timezone to be considered (GMT only, and no DSTs), then I can attempt to solve it, or else I pass on this question.:D Not enough time to spare. lol

    I did some math and then got tired the only thing I can tell is Car A takes 12.05 hours to get at las vegas and Car B takes 12.33 hours to get at okahoma city..

    BTW I don't even know if those cities are at opposite directions or not (that's how I did the math, considering opposite ways) I'm not native american (even though I know more geographic than most of them lol)

    Car A got pulled over for having a empty bud on the dashboard. He doesn't have the funds for bail. He never makes it there.

    Car B crashed in the ass end of a semi - he only makes it to the nearest hospital

    I also got the same answer 12.05 hrs for A and 12.33 hrs for B. Rounding B to the nearest half hour means 12.5 hours, and A will be 12.0 hours. A should arrive at 4 AM, while B should arrive at 4:30 AM. As for the hours apart, my brain stopped working.

    That's great! My poor brain stopped working even before I tried solving it. In fact it went in a spin when I read the OP.:D

    Car A = Will be in Las Vegas at 2:05AM (-2 hours due the time zone (Pacific))
    Car B = Will be in Oklahoma City at 4:33AM (same time zone as Texas (Central))

    Am I right ?? :p

    Don't see how there are more than one right answers..

    At 60mph car A arrives after 12 hours and a 3 minutes (4.03am), while car B arrives after 12 hours and 21 minutes (4.21am) approximately. So they would arrive at 18 minutes interval.

    Now my USA geography sucks, but based on this map that I google-imaged.. i'd say its about 600-700 miles, so that would be 10 hours apart by car, probably about 1h30 y plane and maybe 1 or 2 hours apart by timezone.

    do I win anything? ;)

    There were a couple of answers that were on the right track. The main answer would be they started in mountain time zone. Car a ended in pacific time zone, so he got there at 3:00am, and car b ended in central time zone, so he actually arrived at 5:30am.

    As for part 2. (how far they are apart) time zone wise, they are 2 hours apart, driving time they are 24.5 hours apart.

    Wrong!

    Every math question may have more than one way to find answer; but there is ALWAYS ONLY ONE RIGHT ANSWER.

    Your question also has only ONE right answer.

    I calcuate car A will take 12.05 hours to reach their destination and Car B will take 12.33 hours, so I guess rounded to the nearest half hour they would be 1 half hour apart.

    WOW! Fantastic! huh... care to say all that jargon once again... in lay man's terms?;)

    Treat this as a personal revenge for making my poor brain and some other vital organs go through some unneeded pains...;)

    One of the drivers (still can't work out who though) can commit a few murders in one place and then prove that at the time of murders, he was 24.5 hours driving time away! Hmm.... the judge too would personally commit 1 murder then if he is allowed to... lol


    :D
