two small planes start from the same point and fly in opposite directions the first plane flying 55 mph slower than the second plane. In 2 hours planes are 510 miles apart. Find rate of slower plane
\n" ); document.write( "--------------------
\n" ); document.write( "faster plane DATA:
\n" ); document.write( "rate = x mph ; time = 2 hrs ; distance = 2x miles
\n" ); document.write( "-----
\n" ); document.write( "slower plane DATA:
\n" ); document.write( "rate = x-55 mph ; time = 2 hrs ; distance = 2x-110 miles
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "distance + distance = 510 miles
\n" ); document.write( "2x + 2x - 110 = 510
\n" ); document.write( "4x = 620
\n" ); document.write( "x = 155 mph (faster plane rate)
\n" ); document.write( "----
\n" ); document.write( "x - 55 = 100 mph (slower plane rate)
