Algebra.Com's Answer #561564 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! time/distance=45min/3miles = 15 min to go 1 mi, which is 4 mph \n" ); document.write( ": \n" ); document.write( "Answer to your comment \n" ); document.write( "The formula of course, Speed = dist/time, s = d/t \n" ); document.write( ": \n" ); document.write( "In this problem you are dealing with miles per hour, so we need the times in hrs \n" ); document.write( "45 min = .75 hrs \n" ); document.write( "s = 3/.75 \n" ); document.write( "s = 4 mph \n" ); document.write( " |
