A jogger runs in a straight line with an average velocity of 7.9 m/s for 6.2 min, and then with an average velocity of 1.6 m/s for 4.1 min.
\n" ); document.write( "What is his average velocity during this time?
\n" ); document.write( ":
\n" ); document.write( "Convert to seconds
\n" ); document.write( "6.2*60 = 372 sec
\n" ); document.write( "4.1*60 = 246 sec
\n" ); document.write( "-----------------
\n" ); document.write( "total = 618 sec
\n" ); document.write( ":
\n" ); document.write( "let a = average velocity
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation; dist = speed * time
\n" ); document.write( "(7.9*372) + (1.6*246) = 618a
\n" ); document.write( "2938.8 + 393.6 = 618a
\n" ); document.write( "3332.4 = 618a
\n" ); document.write( "a = \"3332.4%2F618\"
\n" ); document.write( "a = 5.39 m/s is the average velocity\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
