How far west can a pilot go and return in a total time of 3 hours if his air speed is 450 mph and the wind velocity from the west is 5 mph?
\n" ); document.write( "==========
\n" ); document.write( "Let the distanc he can go be \"x\"
\n" ); document.write( "Going west DATA:
\n" ); document.write( "rate= 450-5 =445 mph ; distance = x miles ; time = d/r = x/445
\n" ); document.write( "----------------
\n" ); document.write( "Returning DATA:
\n" ); document.write( "rate = 450+5 = 455 mph; distance = x miles ; time = d/r = x/455
\n" ); document.write( "-----------------
\n" ); document.write( "EQUATIOn:
\n" ); document.write( "time west + time east = 3 hrs
\n" ); document.write( "x/445 + x/455 = 3
\n" ); document.write( "455x + 445x = 3*455*455
\n" ); document.write( "900x= 907425
\n" ); document.write( "x=674.92 miles (This is as far as he can go west)
