distance car traveled when motorcycle departed:
\n" ); document.write( "s = d/t
\n" ); document.write( "d = st
\n" ); document.write( "d = 40*3
\n" ); document.write( "d = 120 miles
\n" ); document.write( "---
\n" ); document.write( "relative speed of two vehicles:
\n" ); document.write( "70-40 = 30 mph
\n" ); document.write( "---
\n" ); document.write( "time when overtake occurs after motorcycle departs:
\n" ); document.write( "s = d/t
\n" ); document.write( "t = d/s
\n" ); document.write( "t = 120/30
\n" ); document.write( "t = 4 hours
\n" ); document.write( "time when overtake occurs after car departs:
\n" ); document.write( "t + 3 = 7 hours
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "distance from starting point when overtake occurs:
\n" ); document.write( "d = 30*7
\n" ); document.write( "d = 210 miles
