First find the distance traveled.
\n" ); document.write( " ( 2 hours )( 45 km/hour ) = 90 miles
\n" ); document.write( "Use distance = rate x time to see how long it takes
\n" ); document.write( "to travel 90 miles at 60 km/hour .
\n" ); document.write( " 90 = time x 60
\n" ); document.write( "divide each side by 60
\n" ); document.write( " 90/60 = time
\n" ); document.write( " 3/2 = time in hours
\n" ); document.write( "
\n" );
