time is equal in this problem\r
\n" ); document.write( "\n" ); document.write( "d=r*t
\n" ); document.write( ":
\n" ); document.write( "t=d/r call the rate for hummingbird r and rate of eagle is r+35
\n" ); document.write( ":
\n" ); document.write( "time t for hummming bird equals 5/r
\n" ); document.write( "time t for eagle equals 8.5/(r+35)
\n" ); document.write( ":
\n" ); document.write( "and since time is equal these are equal to each other:
\n" ); document.write( ":
\n" ); document.write( "5/r=8.5/(r+35)
\n" ); document.write( ":
\n" ); document.write( "cross multiply
\n" ); document.write( ":
\n" ); document.write( "8.5r=5r+175
\n" ); document.write( ":
\n" ); document.write( "3.5r=175
\n" ); document.write( ":
\n" ); document.write( "\"highlight%28r=50%29\" rate of the hummingbird
\n" ); document.write( "\"highlight%28r%2B35=50%2B35=85%29\" speed of the eagle\r
