Im trying to figure out an estimate of how much money I've spent on gas for my truck since I got it. I have put 44,000 miles on it at $50 a fill up (worst case estimate) and I get about 320 miles on a full tank. The answer I got was $6,875. I was wondering if some of you could help me out and tell me if that is what you figured because $6,875 seems too less than what I was guessing. Thanks.

Is it possible for a man cutting logs in the woods to know how fast he is working without a clock? He is also not very good at estimating the time in his head. For example, he normally can cut 30 logs, into 150 smaller logs in 3 hours. How does he know if he is working faster or slower than usual? One way might be how sweaty he gets, or how tired he is, but that could just mean he is taking unnecessary steps or having a bad day.
