Algebra.Com's Answer #435942 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! with a tailwind, a bird flew at a ground speed of 3 miles per hour. flying the same path against the same wind, the bird travels at a ground speed of 1.5 miles per hour. what is the bird's air speed? what is the wind speed? \n" ); document.write( "------ \n" ); document.write( "Equations: \n" ); document.write( "b + w = 3 mph \n" ); document.write( "b - w = 1.5 mph \n" ); document.write( "---- \n" ); document.write( "Add and solve for \"b\": \n" ); document.write( "2b = 4.5 \n" ); document.write( "b = 2.25 mph (bird's speed in still air) \n" ); document.write( "----- \n" ); document.write( "Solve for \"w\": \n" ); document.write( "b + w = 3 mph \n" ); document.write( "2.25 + w = 3 mph \n" ); document.write( "w = 0.75 mph \n" ); document.write( "=================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "=================== \n" ); document.write( " |
