In this question, we're going to use some conversion factors to do some math -related questions asking about a couple of different fuels, traditional gasoline and e85.
00:13
So we're told we get 28 miles per gallon at 350 a gallon for gasoline.
00:19
Overall average mileage for e85 is 22 .5 miles per gallon at 285 a gallon.
00:25
We want to drive 500 miles and know the cost for each of these fuels.
00:30
So as i always tell students with math -related questions, start with what you're given.
00:35
You have 500 miles that you're going to be traveling.
00:38
And you know that here's a conversion factor, that you're going to be able to travel 28 .0 miles per gallon.
00:47
First for the gasoline.
00:51
Let's go ahead and do the same step, traveling the same total mileage, but use the average of 22 .5 miles per gallon for the e85.
01:06
And that will tell us how many gallons of gas we're going to use.
01:09
We're going to save the math till the end, but at this point we're just going to recognize what information that we have at this point when we use that first conversion factor, that we know how many gallons of gas is going to be required to travel 500 miles...
