The question asks for your answer in kilometers per hour.\r
\n" ); document.write( "\n" ); document.write( "kilometers per hour can also be written as \r
\n" ); document.write( "\n" ); document.write( "kilometers/hour\r
\n" ); document.write( "\n" ); document.write( "now replace kilometers with the given value of kilometers and the hours with the given value of hours\r
\n" ); document.write( "\n" ); document.write( "but, since the given value of hours isn't completely in hours we have to convert it.\r
\n" ); document.write( "\n" ); document.write( "a way to do this is to take the extra minutes and divide them by 60. this will give you the equivalent of 9 minutes in hours.\r
\n" ); document.write( "\n" ); document.write( "9/60 = .15\r
\n" ); document.write( "\n" ); document.write( "now we add .15 hours to our original 4 hours and plug it into the equation we made before.
\n" ); document.write( "4+.15 = 4.15 \r
\n" ); document.write( "\n" ); document.write( "18/4.15 = km/h\r
\n" ); document.write( "\n" ); document.write( "thus 4.337km/h is your answer.
\n" ); document.write( "
