relative speed of the two trains:
\n" ); document.write( "70 + 30 = 100 mph
\n" ); document.write( "---
\n" ); document.write( "time when the trains meet:
\n" ); document.write( "s = d/t
\n" ); document.write( "t = d/s
\n" ); document.write( "t = 300/100
\n" ); document.write( "t = 3 hours
\n" ); document.write( "---
\n" ); document.write( "distance traveled by the train that starts at point B, when the trains meet:
\n" ); document.write( "d = st
\n" ); document.write( "d = 70*3
\n" ); document.write( "d = 210 miles
\n" ); document.write( "---
