SOURCE: I need this in decimal form

I'm not clairvoyant, and need more information...
How many days a week does Marla get in the car and mash the gas?

x (in hours) = numminsdrivingperday/60 * numdays

x = (12*2)/60 * numdays

x = 2/5hrs * numdays

x = .4 * numdays

Of course, there MUST be more to it than this, right?

### My mind won't figure this out. I'm going 2500 miles from TN to WA. If I drive 12-14 hours a day how long do you think it would take me to get there?

It will take 33Â±1 hours of driving time.
see https://goo.gl/maps/M8jWjf8Kc8H2
But I would budget for 25% due to traffic and weather conditions.
leave alone the time for sleep, food, bio breaks etc

### How many days would it take to drive 2500 miles if you drove 12-14 hours a day?

It depends on how fast you drive.
It would take about three and a half days at 50mph.
At 60mph you could do it in three days.
At 90mph you could do it in two days and change.

Pull crown out 1 click to set day/date, set to one day behind actual date... Then, pull crown out an additional click to move hour/minute hands around to set exact date by hour/minute a complete 12-24 hour revolution if necessary to get AM or PM accurate for the proper day/date. :)

### Atwood 6 gal w/h won't stay lit longer than 12 minutes

After it is stored for the 2 weeks, do you turn water on to it, then bleed out any air through the taps before lighting it? If not try that and see what happens and let me know if any different.

### Computer disconnected when battery was undone. How long do I need to drive the car before the computer connects again? Trying to take the emmions test and they told me that the computer was disconnected...

Sometimes a few days, starting and running it a few times a day. It could take a week or more. It depends on how many driving cycles and miles. You should run it long enough each time for it to reach full operating temp.

### 1988 Mercedes Benz 300E 3.0L Gasoline F.I. ''Sputtering at Idle

ok..you must have more than one car???? you don't drive the 300 atall im guessing. #1 start car drive up the road and \back to your house. #2 let it idle till problem starts. #3 once it does start with the problem keep it alive with the gas pedal. #4 once your have it safely from dying in higher rpms "rev it" like a kid would, you know like if you were gonna race some one lol. be careful not to over rev or damage engine. you should do this for five minutes no longer than that. #5 let it idle for another 5 minutes. #6 repeat every day until problem with idling decipates. it took mine 3 300e like 3 days of this. if your not going to drive the car once you get the problem out of the way. turn the car on everyday and let it idle for 5 minutes atleast and take it for a short drive once a week. they get lonelly you know lol. later on you can just turn the car on every 2 -3 days and let it idle but still take it on a short drive atleast once a week
