Fuel consumption rate = Fuel used / Distance traveled
First, let's convert the fuel used from liters to milliliters (ml) for convenience in calculations:
Fuel used = 120 L = 120,000 ml
Now we can substitute the given values into the formula:
Fuel consumption rate = 120,000 ml / 3000 km
Simplifying this expression, we get:
Fuel consumption rate = 40 ml/km
This means that the vehicle uses 40 milliliters of fuel to travel 1 kilometer. To convert this to a more commonly used unit of fuel consumption, we can use the conversion factor of 1 L = 1000 ml:
Fuel consumption rate = 0.04 L/km
Finally, to find the rate of fuel consumption in km/h, we need to divide this value by the vehicle's speed in km/h. However, the problem does not provide information about the vehicle's speed, so we cannot determine the fuel consumption rate in km/h.
