Tractors and Power Tillers

During a field drawbar performance test, a tractor delivers a continuous drawbar power of $P_{\text{db}} = 30\text{ kW}$ while consuming diesel fuel at a volumetric rate of $V_f = 9.0\text{ L/h}$. The specific volumetric fuel consumption at the drawbar in $\text{L/kW}\cdot\text{h}$ is ________ (round off to 2 decimal places).
