Hi dear!
\n" ); document.write( "Let m=mike
\n" ); document.write( "P=pete
\n" ); document.write( "B=bill
\n" ); document.write( "From the first sentence,if mike ran 8km more than Bill then,
\n" ); document.write( "m=8+B------(1)
\n" ); document.write( "if pete ran 1km less than three times as Bill,then,
\n" ); document.write( "P=3B-1------(2)
\n" ); document.write( "From your last sentence,
\n" ); document.write( "pete ran 15km further than mike,then,
\n" ); document.write( "P=15+M-----(3)
\n" ); document.write( "now,
\n" ); document.write( "From equ (3),
\n" ); document.write( "M=P-15-----(4)
\n" ); document.write( "put equ (4) in (1)
\n" ); document.write( "P-15=8+B
\n" ); document.write( "P=8+15+B
\n" ); document.write( "P=23+B-----(5)
\n" ); document.write( "Put equ (5) in (2)
\n" ); document.write( "23+B=3B-1
\n" ); document.write( "collect like terms
\n" ); document.write( "3B-B=23+1
\n" ); document.write( "2B=24
\n" ); document.write( "divide both sides by 2
\n" ); document.write( "B=12
\n" ); document.write( "Bill ran 12km
\n" ); document.write( "HOPE THIS HELPS;
