After 30 minutes the first plane has traveled 225 miles from Los Angeles so there are 850-225=625 miles left to Denver. Let t be the time in hours before the 2 planes meet. The first plane will travel 450*t miles. The second plane will travel 520*t miles. The sum of the 2 distances must be 625 miles so. 450*t+520*t=625. 970*t=625. t=625/970. t=0.644 hours. The distance from Denver is 520*0.644=334.88 miles. \n" ); document.write( "
