Algebra.Com's Answer #440290 by jndarrell(58)![]() ![]() ![]() You can put this solution on YOUR website! Your proportion should be set up miles over hours. \n" ); document.write( "You were given a mixed number for the time (4 hours 41 min). I find it easier to do these problems if you convert the minutes into a decimal. So take 41 and divide by 60=0.68 Now your time is 4.68hrs\r \n" ); document.write( "\n" ); document.write( "281/4.68 = x/1 \n" ); document.write( "Cross multiply \n" ); document.write( "4.68x=281 \n" ); document.write( "Divide both sides by 4.68 to get the x alone \n" ); document.write( "x=60.04\r \n" ); document.write( "\n" ); document.write( "Check the instructions you were provided for guidance on rounding. Also don't forget to put the units on your solution.\r \n" ); document.write( "\n" ); document.write( "I would imagine round to a whole number, 60mph \n" ); document.write( " |
