\"the car consumes 6lit/hr when travelling 75km/hr.\"
\n" ); document.write( "'
\n" ); document.write( "Let r= speed and E = fuel consumption rate.
\n" ); document.write( "\"rk=E\";
\n" ); document.write( "\"k=E%2Fr\"
\n" ); document.write( "'
\n" ); document.write( "Putting the given value and computing,
\n" ); document.write( "\"k=6%2F75=2%2F25\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Your question description is unfortunately confusing. My attempt to help is just this:
\n" ); document.write( "90 km/hr means, \"90%282%2F25%29=E\" in liters per hour.
\n" ); document.write( "\"E=7%261%2F5\" liters per hour.
\n" ); document.write( "You say, 20 L were used for the roundtrip, so \"20%2Aliters%281%2Ahour%2F%287.2%2Aliters%29%29=2.78\" hours of roundtrip travel time.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I have no idea what the 6 days and the Sunday information means. You need to clean or clarify your problem description and maybe recheck what question you want to ask.
