\n" ); document.write( "a plane traveled 580 miles to zambaouga and back. the trip there was with the wind. it took 5 hours. the trip back was against the wind. the trip back was 10 hours. find the speed of the plane in still air and the speed of the wind
\n" ); document.write( "

Let speed of plane in still air be S, and wind speed, W
\n" );
document.write( "With total speed with wind being 116 () mph, we get:
\n" );
document.write( "S + W = 116 ------- eq (i)
\n" );
document.write( "With total speed against wind being 58 () mph, we get:
\n" );
document.write( "S - W = 58 -------- eq (ii)
\n" );
document.write( "2S = 174 -------- Adding eqs (i) & (ii)
\n" );
document.write( "S, or speed of plane in still air = , or  mph \n" );
document.write( "

\n" );
