nthabi's car uses 1litres of fuel to travel 12km how many fuel will be needed to travel 420km

Answer 1

To find out how much fuel will be needed to travel 420km, we can set up a proportion:

1 litre / 12 km = x litres / 420 km

Cross-multiplying, we get:

12x = 1 * 420

Simplifying:

12x = 420

Dividing both sides by 12:

x = 35

Therefore, 35 litres of fuel will be needed to travel 420km.
