Question 448732
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.
