A cyclist rides north at 15 km/h and observes that the wind appears to come to him
\n" ); document.write( "from the north-east. On the return journey he rides at the same speed in the opposite
\n" ); document.write( "direction. Now the wind appears to be coming from the south-east. Calculate the true
\n" ); document.write( "speed and direction of the wind.
\n" ); document.write( "=====================
\n" ); document.write( "If by \"from the NE\" you mean an angle of 45 degs, and SE is also 45 degs, then the windspeed is 15 km/hr from the East.
\n" ); document.write( "================
\n" ); document.write( "idk what you mean by \"true speed.\" Is there a false speed?
