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