A motorboat starts out and travels 9 miles an hour. In 3 hours another motorboat rraveling 18 miles an hour starts out to overtake the first one. In how many hours will thei sceond boat overtake the first.
\n" ); document.write( "RELATIVE SPEED WHILE TRAVELLING IN SAME DIRECTIONS = S2-S1=18-9=9 MPH.
\n" ); document.write( "INITIAL DISTANCE OF SEPERATION = DISTANCE TRAVELLED BY FIRST BOAT IN 3 HOURS
\n" ); document.write( " = 3*9=27 MILES.
\n" ); document.write( "FINAL DISTANCE OF SEPERATION=0
\n" ); document.write( "HENCE DISTANCE TO BE COVERED WHEN BOTH BOATS ARE TRAVELLING IN SAME DIRECTION =27-0=27
\n" ); document.write( "TIME TAKEN =DISTANCE / RELATIVE SPEED = 27 / 9 = 3 HRS.
\n" ); document.write( "
\n" );
