a train 100 meter long completely passes a man walking in the same direction at 2km/h in 9seconds.
\n" ); document.write( ":
\n" ); document.write( "Find the speed in the relation to the man in meters/sec
\n" ); document.write( "100/9 = 1l.11 m/sec
\n" ); document.write( "In km/h: $\"%28%283600%2A11.11%29%29%2F1000\"$ = 40 km/h in relation to the man
\n" ); document.write( "Who is walking at 2 km/h, therefore Actual train speed is 42 km/h
\n" ); document.write( ":
\n" ); document.write( " and a car traveling in opposite direction in 3 second at what speed was the car traveling?
\n" ); document.write( ":
\n" ); document.write( "Find the speed in relation to the car:
\n" ); document.write( "100/3 = 33.3 m/sec
\n" ); document.write( "In km/h: $\"%28%283600%2A33.33%29%29%2F1000\"$ = 120 km/hr
\n" ); document.write( "Since the train (42 km/hr) and car (s) are going in the opposite direction, their relative speed is the sum of the car speed and the train speed
\n" ); document.write( "s + 42 = 120
\n" ); document.write( "s = 120 - 42
\n" ); document.write( "s = 78 km/hr is the actual speed of the car
