If the return trip took 45 minutes, find the wind speed and the speed at which David pedals with no wind (to the nearest mile per hour). \n" ); document.write( "
Algebra.Com's Answer #729917 by Alan3354(69443) You can put this solution on YOUR website! Bike speed is not linearly related to windspeed. \n" ); document.write( "Not a reasonable question/problem. \n" ); document.write( "======== \n" ); document.write( "If you bike at 10 mi/hr with a 10 mi/hr crosswind, it does not make your ground track 45 degrees from your heading, right? \n" ); document.write( "If you don't pedal at all, does the wind move you and the bicycle? \n" ); document.write( "----- \n" ); document.write( "The force from the wind is a function of the square of the windspeed. \n" ); document.write( " |
