a train running at the speed of 60 km / hr crosses a pole in 3 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 x 3 / 3 m = 50 m . answer : option d"
multiply(divide(multiply(60, const_1000), const_3600), 3)
