Best Answer

Light travels for precisely one second each second.

During that time, it travels a distance of about 300 million meters, or 186 thousand miles, if it's traveling
in vacuum, a bit less if it has to plow its way through any material medium.

How long by car would it take to travel on US route 66 in one second of a light year?

The question can't be answered. At least not in its present incomprehensible form. -- "light year" is a distance -- "one second" of that distance is meaningless -- "how long ... in one second" seems even less so If you mean, how long would it take a to travel one light second by car, then the answer would be something like this: One light second equals 186,000 miles. Assuming that the car travels at the speed limit of 70 miles/hour, it would take 186,000/70 = 2657 hours = 110 days 17 hours to travel one light second.


If you could travel 299792458 in a second and you needed to travel 93000000 miles how long would it take?

You're asking how long it takes light and heat to travel from the sun to the earth, but mixing your units.The "299 ... ...' is the speed of light in meters per second, and the "93 ... ..." is the distance in miles.The answer is still 8-1/3 minutes.
