document.write( "Question 1066369: This is an Algebra 1 question: David rode his bike east at 20 mi/hr for 36 min with a tailwind. He then turned around to ride home along the same route against the wind. If the return trip took 45 min, find the wind speed and the speed at which David pedals with no wind (to the nearest mile per hour). Thank you so much on this! I not only need the answer but HOW it was solved. \n" ); document.write( "
Algebra.Com's Answer #681563 by Alan3354(69443) You can put this solution on YOUR website! The speed of a bicycle is not linearly related to windspeed. \n" ); document.write( "If the wind blows from the right side, it doesn't cause a bicycle to change its direction. \n" ); document.write( "---- \n" ); document.write( "It's another instance of people writing math problems and books who do not know what they're talking about. \n" ); document.write( "================ \n" ); document.write( "If the relation between bike speed and windspeed is defined it would be a viable problem. The wind effects are likely a function of the square of the relative windspeed, but it's not up to anyone to assume that. \n" ); document.write( "----------------------------- \n" ); document.write( "The solution by another tutor would apply to airplanes and to boats, but not to bicycles, walking, running, or roller skating. \n" ); document.write( " |
