A bus travels 42 km with 6 liters of petrol. How many liters of petrol does is need for a distance of 413km?

1 answer

Let x be the amount of petrol needed for a distance of 413 km.

We can set up a proportion:

6 liters is to 42 km as x liters is to 413 km

6/42 = x/413

To solve for x, we can cross-multiply:

6 * 413 = 42 * x

2478 = 42x

Dividing both sides by 42:

x = 59 liters

Therefore, the bus needs 59 liters of petrol for a distance of 413 km.
