a train running at the speed of 60 km / hr crosses a pole in 6 seconds . what is the length of the train ?
"speed = 60 x 5 / 18 m / sec = 50 / 3 m / sec . length of the train = ( speed x time ) . length of the train = 50 / 3 x 6 m = 100 m . option c"
multiply(divide(multiply(60, const_1000), const_3600), 6)
