You can put this solution on YOUR website!
What we want to do here is a unit conversion. We want to convert our kilometers to hours. Our conversion rate is 356 km = 1 hr. Therefore we can say:\r
\n" ); document.write( "\n" ); document.write( "1424km X 1hr/356km = 4 hrs.\r
\n" ); document.write( "\n" ); document.write( "Our km units cancel out and we are left with only hrs.\r
\n" ); document.write( "\n" ); document.write( "Hope this helps!
