First, let's calculate how many laps the car will be able to complete on a full tank of gas.
Since the car has 40 gallons of gas and goes around a 2.5-mile track, it can travel for 40 * 2.5 = 100 miles on a full tank.
If the car is going for 500 miles, it will need to refill after 500 / 100 = 5 times around the track.
if a car has 40 gallons of gas and they go at an average speed of 200 mph around a 2.5 mile track how many times will the have to refill after 500 miles
