You can put this solution on YOUR website!
Distance = rate x time
\n" ); document.write( "or
\n" ); document.write( " $\"+d+=+r%2At+\"$
\n" ); document.write( "--------------
\n" ); document.write( "You are given:
\n" ); document.write( " $\"+d+=+50+\"$ m
\n" ); document.write( " $\"+r+=+45+\"$ km/hr
\n" ); document.write( "----------------
\n" ); document.write( "First, you have to convert
\n" ); document.write( "meters to km
\n" ); document.write( "In terms of just units:
\n" ); document.write( "( m ) * ( km/m ) = km
\n" ); document.write( " $\"+50%2A%28+1%2F1000+%29+=+.05+\"$ m
\n" ); document.write( "-------------------------
\n" ); document.write( "Now units are compatible
\n" ); document.write( " $\"+d+=+r%2At+\"$
\n" ); document.write( " km = ( km/hr) x hrs
\n" ); document.write( "-------------------
\n" ); document.write( " $\"+.05+=+45t+\"$
\n" ); document.write( " $\"+t+=+.05%2F45+\"$
\n" ); document.write( " $\"+t+=+1%2F900+\"$ hrs
\n" ); document.write( "-----------------
\n" ); document.write( "Convert hrs to min
\n" ); document.write( " $\"+%28+1%2F900+%29%2A60+=+4%2F60+\"$
\n" ); document.write( "------------------------
\n" ); document.write( "Convert min to sec
\n" ); document.write( " $\"+%28+4%2F60+%29%2A60+=+4+\"$
\n" ); document.write( "-------------------
\n" ); document.write( "It takes 4 sec to travel 50 m at 45 km/hr\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
