a)
\n" ); document.write( "speed
\n" ); document.write( "b)
\n" ); document.write( "D=rt
\n" ); document.write( "r=D/t
\n" ); document.write( "c)
\n" ); document.write( "r=275/5.5=50 mph
\n" ); document.write( "t=D/r
\n" ); document.write( "t=350/50
\n" ); document.write( "t=7 hrs
\n" ); document.write( "d)
\n" ); document.write( "D=rt
\n" ); document.write( "50*4=200 mi
\n" ); document.write( "
\n" );
