total time in seconds:
\n" ); document.write( "t = 5 + (2 min * 60 sec/min) + (17 min * 60 sec/min) + 32
\n" ); document.write( "t = 5 + (120) + (1020) + 32
\n" ); document.write( "t = 1177 sec
\n" ); document.write( "---
\n" ); document.write( "total distance in meters:
\n" ); document.write( "d = 15 + (3 km * 1000 m/km)
\n" ); document.write( "d = 15 + (3000)
\n" ); document.write( "d = 3015 meters
\n" ); document.write( "---
\n" ); document.write( "s = d / t
\n" ); document.write( "---
\n" ); document.write( "s = 3015 / 1177 = 2.562 m/sec
