A car leaves Manila, heading toward a resort, at an average speed of 60 miles per hour. On a parallel track, another car leaves Manila a half hour later and travels at an average speed of 90 milers per hour. At what point will Car B pass car A?
\n" ); document.write( ".
\n" ); document.write( "Apply the distance formula:
\n" ); document.write( "d = rt
\n" ); document.write( "where
\n" ); document.write( "d is distance
\n" ); document.write( "r is rate or speed
\n" ); document.write( "t is time
\n" ); document.write( ".
\n" ); document.write( "Let x = time traveled
\n" ); document.write( "then
\n" ); document.write( "\"distance traveled by car A\" = 60x
\n" ); document.write( "\"distance traveled by car B\" = 90(x-.5)
\n" ); document.write( ".
\n" ); document.write( "Car B will pass car when their distance are equal:
\n" ); document.write( "60x = 90(x-.5)
\n" ); document.write( "60x = 90x-45
\n" ); document.write( "45 = 30x
\n" ); document.write( "45/30 = x
\n" ); document.write( "1.5 hours = x
\n" ); document.write( "(time Car B will pass Car A)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
