An athlete covers a total distance of 32km frpm point C to point S.
\n" ); document.write( "First he walks at a speed of 6km/hr to point G.
\n" ); document.write( "He finally runs at a speed, which is three times as fast as before, for 12km from point G to S.
\n" ); document.write( "----
\n" ); document.write( "1st part DATA:
\n" ); document.write( "rate = 6 km/hr ; distance = 32-12 = 20 km ; time = 20/6 hr = 3 1/3 hr
\n" ); document.write( "2nd part DATA:
\n" ); document.write( "rate = 18 km/hr; distance = 12 km ; time = 12/18 = 2/3 hr
\n" ); document.write( "--------------------
\n" ); document.write( " 1.Calculate the total time in hours taken to complete journey CS.
\n" ); document.write( "Total time = 3 1/3 + 2/3 = 4 hrs
\n" ); document.write( "----------------------------------------
