What is the relation between specific air range and specific enurance?

1.	What is the relation between specific air range and specific enurance?(a) SAR=VSE(b) SAR=\(\frac{V}{SE}\)(c) SE=VSAR(d) SE=\(\frac{V}{SAR}\)I have been asked this question in an interview for job.My question is from Range and Endurance for Aircraft with Power Producing Engines in chapter Cruising Performance of Aircraft Performance
Answer» The correct ANSWER is (a) SAR=V*SE The explanation: The formula for specific air range is given by: SAR=\(\FRAC{V}{CP}\) where v is velocity, C is specific FUEL CONSUMPTION and P is power. The formula for specific ENDURANCE is given by: SE=\(\frac{1}{CP}\) where C is specific fuel consumption and P is power.
