Lois rides her bike to visit a friend. she travels 10 mph. while shes there it starts to rain\r
\n" ); document.write( "\n" ); document.write( "Let the friend's house be x miles away.
\n" ); document.write( "Time taken to reach friend's house x/10 hours\r
\n" ); document.write( "\n" ); document.write( "Her friend drives her home in a car traveling at 25 mph.
\n" ); document.write( "Time taken to drive back = x/25 hours\r
\n" ); document.write( "\n" ); document.write( " It takes Lois 1.5 hours longer to go to her friends than it does to return home.\r
\n" ); document.write( "\n" ); document.write( "Time taken to bike to friend.s house - time return by car = 1.5\r
\n" ); document.write( "\n" ); document.write( "x/10 - x/25 = 3/2
\n" ); document.write( "Multiply by LCD 50\r
\n" ); document.write( "\n" ); document.write( "5x-2x= 75\r
\n" ); document.write( "\n" ); document.write( "3x=75\r
\n" ); document.write( "\n" ); document.write( "x = 25 miles\r
\n" ); document.write( "\n" ); document.write( " how many hours did it take Lois to ride to her friends house?\r
\n" ); document.write( "\n" ); document.write( "time = distance / speed = 25/10 = 2.5 hourw\r
\n" ); document.write( "\n" ); document.write( "it took Lois 2.5 hours to ride to her friend's house.
\n" ); document.write( " \n" ); document.write( "
