3 The fuel consumption of an airplane is measured in gal/mi (gallon per mile) or in Lkm (liter per kilometers). Write a MATLAB user-defined function that converts fuel efficiency consumption from gal/mi to LIcm. For the function name and arguments, use Lkm-LkmToGalm (gmi). The input argument gmi is the consumption in gal/mi, and the output argument Lkm is the con-one sumption in L/km. Use the function in the Command Window to: (a) Determine the fuel consumption in l/km of a Boeing 747 whose fuel con- sumption is about 5 gal/mi. (b) Determine the fuel consumption in Lkm of the Concorde whose fuel con- sumption is about 5.8 gal/mi. m l
