A jogger leaves home and runs at a constant speed of 4 miles per hour. Nine minutes later a bicyclist follows along the same route at a constant speed of 15 miles per hour. Find the bicyclists travel time needed to catch the jogger.
\n" ); document.write( "-------------------
\n" ); document.write( "Jogger DATA:
\n" ); document.write( "rate = 4 mph ; time = x hrs ; distance = 4x miles
\n" ); document.write( "-------------------
\n" ); document.write( "Bicyclist DATA:
\n" ); document.write( "rate = 15 mph ; time = x-(9/60) hrs ; distance = 15[x-(9/60)] miles
\n" ); document.write( "-------
\n" ); document.write( "Equation:
\n" ); document.write( "distance = distance
\n" ); document.write( "4x = 15x - (9/4)
\n" ); document.write( "11x = 9/4
\n" ); document.write( "x = 9/44 hrs.
\n" ); document.write( "x = (9/44)60 = 12.27 minutes
\n" ); document.write( "-----
\n" ); document.write( "Bicyclist's time: 12.27 min - 9 min = 3.27 minutes
\n" ); document.write( "==============
