To determine how many liters of petrol are required to cover a distance of 11 km, we can use the given information about the bike's fuel efficiency.
If the bike can travel 45 km on 1 liter of petrol, we can calculate the fuel consumption per kilometer by dividing the distance by the fuel efficiency:
Fuel consumption per kilometer = 1 liter / 45 km ≈ 0.0222 liters/km
Now we can determine the fuel required for 11 km by multiplying the distance by the fuel consumption per kilometer:
Fuel required for 11 km = 11 km * 0.0222 liters/km ≈ 0.2442 liters
Therefore, approximately 0.2442 liters of petrol would be required to cover a distance of 11 km.
