Algebra.Com's Answer #579334 by macston(5194)![]() ![]() You can put this solution on YOUR website! A: RATIO: 90 mi is to 330 mi as 1.5 hours is to x: \n" ); document.write( "90 mi/330 mi=1.5 hr/x Multiply each side by 330x miles \n" ); document.write( "(90 mi)x=(1.5 hr)(330 mi) Divide each side by 90 miles \n" ); document.write( "x=1.5 hr(330 mi)/90 mi=495 hr/90=5.5 hrs \n" ); document.write( "B: Using d=rt \n" ); document.write( "d=rt \n" ); document.write( "r=d/t=90 mi/1.5 hr=60 mi/hr \n" ); document.write( "t=d/r=330 mi/60 mi/hr=5.5 hrs \n" ); document.write( " |
