Question 448732: If you enter Interstate 40 at mile marker 23 in Sayre, Oklahoma, how far would you need to travel to reach mile marker 125 in El Reno, Oklahoma? After reaching El Reno, you might worry that your vehicle is running low on fuel. You know that your vehicle can travel 32 miles per gallon (miles/gallon).
Write an inequality that shows the mile markers (m) that you can reach from El Reno, travelling in either direction, when g is the amount of fuel, in gallons, in your vehicle. Explain what this means.

You can put this solution on YOUR website! Distance from Sayre to El Reno = 125 – 23 = 12 miles
We would need to travel 102 miles
When you reach El Reno, you have g gallons of gas left. So, you could cover up to 32g miles. But this journey can be either direction of El Reno. You can thus drive up to the mile marker (125 + 32g) or up to the mile marker (125 - 32g) before having an empty tank.
