The information below comes from a test carried out on a petrol engine in a motor car. power output: $150\,\text{kW}$ fuel consumption: $20$ litres per hour energy content of fuel: $40\,\text{MJ}$ per litre Determine the ratio $\dfrac{\text{power output}}{\text{power input}}$?
- A$\dfrac{150\times10^3}{40\times10^6\times20\times60\times60}$
- B$\dfrac{150\times10^3\times60\times60}{20\times40\times10^6}$
- C$\dfrac{150\times10^3\times40\times10^6\times20}{60\times60}$
- D$\dfrac{150\times10^3\times20}{40\times10^3\times60\times60}$
