Okay, so we have then 14 gallons of gas in the tank.
00:04
So we'll say g is the gas in the tank.
00:08
It starts with 14 gallons.
00:11
And 25 miles per gallon, and we'll say distance moved.
00:17
So this means that the gallons you have starts off at 14.
00:25
So when d is zero, you have 14 gallons in the tank.
00:31
As you move, it will decrease.
00:33
Now every 25 miles you go, you will use up one gallon gas.
00:44
So d over 25 goes here.
00:50
Quick check, if d is 25 miles, if you use one gallon, there are 13 gallons left...
