Question 1042873
your solution is that the cost for the american car is equal to the cost for the european car when they have both traveled 1,022,019.993 kilometers.
that's 1 million, 22 thousand, 19.993 kilometers.
divide kilometers by 1.60934 to get an equivalent 635,055.36 miles.
that's a lot of miles, but then again, the cost per gallon is very cheap.
.85 per gallon is a lot cheaper than 3.00 per gallon, which it is today.


if you said that the cost of fuel is .85 per liter, then that might have made more sense in today's environment because .85 * 3.78541 = 3.2175985 per gallon which is a lot closer to what it is today.


but you said .85 per liter and i worked the problem that way.

if i use 3.2175985 per gallon, then i get .85 per liter and the number of kilometers changes as follows:


break even point becomes 269,989.2463 kilometers.
divide that by 1.60934 kilometers per mile to get an equivalent 167,763 miles.


that's still a lot of miles, but it's a lot more believable since most cars nowadays will get you somewhere between 100,000 miles and 200,000 miles of travel before they need major overhauls.
