All right, so this question is like a come up with your own question.
00:04
All they're telling you is you need to figure out how much money it would cost to drive from new york to chicago.
00:12
And you have to come up with all your variables in a way, all your information.
00:18
So what i did was i just went on my maps application on my cell phone and i typed in new york, chicago.
00:24
It says it takes 794 miles to drive from new york to chicago.
00:29
Ago, right? so if you're starting with miles and you have to eventually end up with dollars, then what's going to be your, what are your two unit conversions, right? can you go from miles to dollars? probably not, not right? you can't go straight from miles to dollars.
00:51
When you're driving, you have to factor in what's making the cargo, which is gasoline, right? so how much is gas cost? so that's how you bring the dollar signs.
00:59
That's how you bring the unit of money into this problem.
01:03
So you look up the average price of gas right now in the country.
01:06
So you could use the new york state gas price, assuming that, i mean, if you're leaving from new york, the average gas price is, whatever that number is, i took the national gas price right now, which is $2 .79 per gallon.
01:21
And then you need a way to go from miles to gallons, most likely, right? if you're not going from miles to dollars, you have to use gallon.
01:29
As your unit conversion.
01:32
So that goes back to your car's efficiency.
01:35
So let's say that a good four -door sedan car probably uses 25 miles to the gallon, right? you probably get 25 miles to the gallon, so you can use that as a way to get to gallons from miles and then use the price of gas to get from gallons to dollars.
01:55
And that's how you answer this problem.
01:56
Right, so you could set up your dimensional analysis...
