A car can travel 400 miles on a full tank of petrol. A more efficient car can travel 32% further. How many miles can it travel on a tank?

Answer 1

Answer:

Answer:160 miles

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 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
