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 200 miles
First, we need to calculate the number of laps the car can make on the 2.5 mile track with 40 gallons of gas.
Assuming the car's fuel efficiency is constant at 10 miles per gallon (40 gallons * 10 miles/gallon = 400 miles), the car can go for 400 miles with a full tank of gas.
After 200 miles, the car will have used up 20 gallons of gas (200 miles / 10 miles/gallon = 20 gallons).
So, the car will need to refill after 20 gallons / 40 gallons per full tank = 0.5 times.
Therefore, the car will need to refill once after 200 miles.
