A motorist traveled along a straight road from Town A to Town B at 70 km/h.
\n" ); document.write( " A motorcyclist traveled from Town B to Town A at 80 km/h.
\n" ); document.write( " Both started the journeys at the same time and traveled on the same road.
\n" ); document.write( " If they passed each other after traveling for 1 hour 40 minutes,
\n" ); document.write( " find the distance between Town A and Town B.
\n" ); document.write( " How long did the motorcyclist take to travel his whole journey?
\n" ); document.write( ":
\n" ); document.write( "Let d = distance between towns A & B; (dist = speed * time)
\n" ); document.write( ":
\n" ); document.write( "Change 1 hr 40 min to 1\"2%2F3\" = \"5%2F3\" hrs
\n" ); document.write( ":
\n" ); document.write( "When the car meets the motorcycle, they will have traveled the A-B distance
\n" ); document.write( ":
\n" ); document.write( "Total dist = car dist + motorcycle dist
\n" ); document.write( "d = 70*\"5%2F3\" + 80*\"5%2F3\"
\n" ); document.write( "d = \"350%2F3\" + \"400%2F3\"
\n" ); document.write( "d = \"750%2F3\"
\n" ); document.write( "d = 250 km from A to B
\n" ); document.write( ":
\n" ); document.write( "Motorcycle travel time = \"250%2F80\" = 3.125 hrs which is 3 hr 7.5 min
\n" ); document.write( "
\n" );
