YOU ARE IN A SPEED BOAT ON A RIVER MOVING IN THE SAME DIRECTION AS THE CURRENT. THE SPEEDOMETER ON THE BOAT SHOWS THAT ITS SPEED IS 20 KM/H. HOWEVER, A PERSON ON THE SHORE MEASURES THE BOAT'S SPEED AS 23 KM/H. HOW IS THIS POSSIBLE?
\n" ); document.write( "------------------
\n" ); document.write( "The speedometer does not measure the speed of the current; it
\n" ); document.write( "measures the speed of the boat thru the water.
\n" ); document.write( "actual speed - current speed = 20 km/hr
\n" ); document.write( "The observer sees that combined speed of the boat and the current.
\n" ); document.write( "actual speed + current = 23 km/hr
\n" ); document.write( "----
\n" ); document.write( "Speed of the current is 3 km/hr
\n" ); document.write( "--------
