Algebra.Com's Answer #276001 by gwendolyn(128)![]() ![]() You can put this solution on YOUR website! We use the formula distance = rate * time. The only trick is using consistent units since 3 hours and 24 minutes is a mixture of hours and minutes.\r \n" ); document.write( "\n" ); document.write( "Let's change that into an improper fraction using the fact that there are 60 minutes in an hour. 3 hours and 24 minutes is the same as 3 and 24/60 hours. \n" ); document.write( "So:\r \n" ); document.write( "\n" ); document.write( "3 and 24/60 = 3*(60/60) and 24/60\r \n" ); document.write( "\n" ); document.write( "180/60 + 24/60 = 204/60 hours\r \n" ); document.write( "\n" ); document.write( "Now we can use the formula:\r \n" ); document.write( "\n" ); document.write( "distance = 55 * 204/60\r \n" ); document.write( "\n" ); document.write( "distance = 187 miles\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
