Algebra.Com's Answer #336133 by Alan3354(69443) You can put this solution on YOUR website! Simpson drives his car with an average velocity of 46.2 km/h to the east. How long will it take him to drive 159 km on a straight highway? Answer in units of h \n" ); document.write( "-------------- \n" ); document.write( "d = r*t \n" ); document.write( "t = d/r \n" ); document.write( "t = 159 km/46.2 km/hr \n" ); document.write( "-------------------- \n" ); document.write( "I tried multiplying the 46.2 time the 159 kilometers because thats what i got by manipulating the formula of average velocity which is displacement/total time traveled, but i got 7,345.8 and that is way too long.. \n" ); document.write( "------------ \n" ); document.write( "46.2 km * 159 km/hr --> some number with units of km^2/hr \n" ); document.write( "km^2/hr is obviously wrong. Use the units to see if you're doing it the right way.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
