Algebra.Com's Answer #444838 by KMST(5328)![]() ![]() You can put this solution on YOUR website! After 2.5 hours, plane A is directly to the West of Kansas City at a distance (in miles) of \n" ); document.write( " \n" ); document.write( "After 2.5 hours, plane B is directly South of Kansas City at a distance (in miles) of \n" ); document.write( " \n" ); document.write( "The trajectories of the two planes form a right angle. \n" ); document.write( "Along with the segment connecting the two planes, they form a right triangle with the trajectories for legs and the distance between the planes, d (in miles), for hypotenuse. \n" ); document.write( "According to the Pythagorean theorem, \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "The exact value is \n" ); document.write( "A good approximation is \n" ); document.write( "After 2.5 hours the planes are about 1425 miles apart. \n" ); document.write( " |
