Find the speed of the plane in still air and the speed of the wind. So far I've tried making a table, but I didn't know what columns were needed and I don't think it's a D=RT problem. I also thought maybe converting km/h to mph might be helpful, but so far it hasn't been. Your help would be greatly appreciated and I want to thank you for tutoring us kids/teens for free :) \n" ); document.write( "

Flying with the wind a plane went 183 km/h. Flying into the same wind the plane only went 141km/h. Find the speed of the plane in still air and the speed of the wind.
\n" ); document.write( "=================
\n" ); document.write( "Let plane speed in still are be \"p\".
\n" ); document.write( "Let wind speed be \"w\"
\n" ); document.write( "------------------
\n" ); document.write( "Equations:
\n" ); document.write( "p + w = 183 km/h
\n" ); document.write( "p - w = 141 km/h
\n" ); document.write( "-----------------
\n" ); document.write( "Add and solve for \"p\":
\n" ); document.write( "2p = 323
\n" ); document.write( "plane speed in still air = 161.5 km/hr
\n" ); document.write( "------
\n" ); document.write( "Solve for \"w\":
\n" ); document.write( "p + w = 183
\n" ); document.write( "161.5 + w = 183
\n" ); document.write( "wind speed = 21.5 km/hr
