The circles of longitude, meridians, meet at the geographical poles, with the west-east width of a second naturally decreasing as latitude increases. On the equator at sea level, one longitudinal second measures 30.92 metres, a longitudinal minute is 1855 metres and a longitudinal degree is 111.3 kilometres.
The median average insurance rate in the U.S. is $1,248 per year, which works out to just about $100 per month in insurance. Assuming $125 per month for gas, and $50 per month to save for things like registration and repairs, that leaves our hypothetical buyer with $277 for their monthly car payment.
This is about 113 gallons per month. AT my most recent fill-up (my vehicle demands premium) the cost per gallon was $3.199. So the monthly estimate is about $360 per month. This is to drive an estimated 72.8 miles per day (again, on a seven day per week basis).
