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

Convert everything to kg first
12g = 0.012kg
2500mg = 0.0025kg
0.23 tonnes = 230kg
so
2500mg, 12g, 0.23 tonnes, 4600kg
2*2*3*5 are the prime factors of 60
