Re: Gas prices and you
another way to look at this - if you have a car and a job, figure out the total cost of driving your car (per mile)
and figure out how many hours you have to work for each hour you drive your car
then you can calcuate your real 'speed' when you drive
for example: lets say you drive one hour a day to and from work, at 65mph
speed = 65 miles / 1 hour = 65mph
but your car is costing you 40 cents a mile to drive (total cost like I mentioned previously), then to go 65 miles costs you $26.
if you make $7 an hour at work, then for each hour you drive you are working $26 / 7 = 3.7 hrs
add that back into the speed equation. To drive your car 65 miles takes an hour + you must work 3.7 hrs for each hour you drive:
65 miles / (1 + 3.7) = 13.8 mph (real speed)
Ironically, the more expensive your car is (ie, Mustang, Lexus...) the lower your real speed will be!
I have to point out, a healthy young adult can easily average 15mph on a 27" ten speed bicycle (and you can usually find them at garage sales for $25).
