I came up with A.
Looking at it in terms of miles driven per year I came up with the following:
Driving 12,000 miles/yr you consume the following fuel amounts.
A)
10mpg = 1200 gallons of fuel
20mpg = 600 gallons of fuel
1200-600=600 gallons of fuel saved.
B)
25mpg = 480 gallons of fuel
50mpg = 240 gallons of fuel
480-240=240 gallons of fuel saved.
Using any amount of miles driven in a year, A will always save more gallons of fuel. Do I get a cookie?
Doesn't matter when he's only using his (I'm going to assume) truck to haul a few things a total of 20 miles a month. Then he'll use his civic or (now upgraded to super-hybrid) to drive all the rest of the time.
OK, now i can see where you mean "which saves more gas, not USES less.." I guess. In that case RX007 is correct. You would save more gas (yay environment?) if you decided to switch to just using that one automobile.
I'm also tunnel-visioning it as seeing you keeping both cars. Will you be getting rid of one? Or using both?
Question is too vague!
