Answer:

Answer:160 miles


Step-by-step explanation:

You can work out this type of question by using the 'unitary' method, which means finding out how much for ONE.


If you set out the steps with short sentences it will be clearer.


On 15 gallons, a car can travel 400 miles÷15↓

On 1 gallon, a car can travel 400÷15=262


miles


Once you know the distance travelled on 1 gallon of fuel, you can work out the distance travelled for any number of gallons.


On 6 gallons the car can travel
