a man walking at the rate of 5 km / hr crosses a bridge in 15 minutes. the length of the bridge ( in meters ) is:
multiply(divide(multiply(5, const_1000), const_60), 15)
"speed = ( 5 * 5 / 18 ) m / sec = 25 / 18 m / sec . distance covered in 15 minutes = ( 25 / 18 * 15 * 60 ) m = 1250 m . correct option : d"
