Jonathan leaves home at 07:45 and arrives at the office at 09:30.
\n" ); document.write( " The journey is 42 miles.
\n" ); document.write( ":
\n" ); document.write( "I think you are on the right track, maybe if I just run thru it,
\n" ); document.write( "it will clarify things in your mind
\n" ); document.write( ":
\n" ); document.write( "Find his travel time: 09:30 - 07:45 = 1 hr 45 min
\n" ); document.write( "change 1 hr 45 to hrs: 1 + 45/60 = 1.75 hrs (decimals will work here)
\n" ); document.write( ":
\n" ); document.write( "Speed = dist/time
\n" ); document.write( "S = \"42%2F1.75\"
\n" ); document.write( "S = 24 mph is the av speed
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "We can check that by finding the distance using a time of 1.75 hrs and 24 mph
\n" ); document.write( "1.75 * 24 = 42 mi
\n" ); document.write( "
\n" );
