to attend a wedding Barbara starts driving west from Woodstock at 80km/h. One hour later, Barbara's parents leave Woodstock and drive along the same road at 100 km/h. At what distance from Woodstock will Barbara's parents pass her?
\n" ); document.write( ":
\n" ); document.write( "let d = distance when this occurs
\n" ); document.write( ":
\n" ); document.write( "Write a time equation: time = \"dist%2Fspeed\"
\n" ); document.write( ":
\n" ); document.write( "B's time = P's time + 1 hr
\n" ); document.write( "\"d%2F80\" = \"d%2F100\" + 1
\n" ); document.write( "Multiply eq by 400:
\n" ); document.write( "400*\"d%2F80\" = 400*\"d%2F100\" + 400(1)
\n" ); document.write( "cancel out the denominators
\n" ); document.write( "5d = 4d + 400
\n" ); document.write( "5d - 4d = 400
\n" ); document.write( "d = 400 km from W.
