The first friend runs at a speed of 8 miles per hour.
\n" ); document.write( "The second friend runs at a speed of 7 miles per hour. \r
\n" ); document.write( "\n" ); document.write( "they left at 6 p.m.
\n" ); document.write( "their houses are 20 miles apart, \r
\n" ); document.write( "\n" ); document.write( "Since they are running towards each other the effective speed will be (8+7) = 15 mph\r
\n" ); document.write( "\n" ); document.write( "Distance = 20 miles
\n" ); document.write( "time they run = 20/15 =4/3 hours\r
\n" ); document.write( "\n" ); document.write( "They meet at 7.20 pm\r
