an airplane A leaves los angeles for denver at a speed of 450 mph. thirty minutes later a plane B going from denver to los angeles leaves denver which is 851 miles from los angeles at a speed of 489 mph. when they meet how far are they apart from denver?
\n" ); document.write( "-----
\n" ); document.write( "LA to Denver DATA:
\n" ); document.write( "rate = 450 mph ; time = x hrs ; distance = r*t = 450x miles
\n" ); document.write( "-----
\n" ); document.write( "Denver to LA DATA:
\n" ); document.write( "rate = 489 mph ; time = x-0.5 hrs ; distance = r*t = 489(x-0.5) miles
\n" ); document.write( "--------
\n" ); document.write( "Equation:
\n" ); document.write( "dist + dist = 851 miles
\n" ); document.write( "450x + 489x - 489(0.5) = 851
\n" ); document.write( "939 x = 851 + 244.5
\n" ); document.write( "-----
\n" ); document.write( "939x = 1095.5
\n" ); document.write( "x = 7/6 hr.
\n" ); document.write( "---
\n" ); document.write( "Distance from Denver: (7/6)489 = 570.5 miles
