A small plane flew 1030 miles in 5 hours with the wind. Then on the return trip, flying against the wind, it traveled only 730 miles in 5 hours. What were the wind velocity and the speed of the plane?
\n" ); document.write( "----
\n" ); document.write( "With-wind DATA:
\n" ); document.write( "distance = 1030 miles ; time = 5 hrs ; rate = 206 mph
\n" ); document.write( "----
\n" ); document.write( "Against-wind DATA:
\n" ); document.write( "distance = 730 miles ; time = 5 hrs ; rate = 146 mph
\n" ); document.write( "-------
\n" ); document.write( "Equations:
\n" ); document.write( "p + w = 206 mph
\n" ); document.write( "p - w = 146 mph
\n" ); document.write( "-----
\n" ); document.write( "Add and solve for \"p\"::
\n" ); document.write( "2p = 352
\n" ); document.write( "p = 176 mph (plane speed with no wind)
\n" ); document.write( "----
\n" ); document.write( "Solve for \"w\"::
\n" ); document.write( "Sutract and solve for \"w\":
\n" ); document.write( "2w = 60
\n" ); document.write( "w = 30 mph (wind speed)
