a train takes 10 sec to pass a signal post and covers a distance of 10 km in 15 min . find the length of train ?
explanation : we know , speed = distance / time speed = 10 / 50 x 60 = 40 x 5 / 18 m / sec = 11.1 m / sec length of train = ( speed x time ) = ( 11.11 x 10 ) = 111.1 m answer is c
multiply(divide(multiply(const_1000, 10), multiply(const_60, 15)), 10)
