a train 110 m long is running with a speed of 30 km / hr. in what time will it pass a man who is running at 6 km / hr in the direction opposite to that in which the train is going?
divide(110, multiply(add(30, 6), const_0_2778))
"speed of train relative to man = 30 + 6 = 36 km / hr . = 36 * 5 / 18 = 10 m / sec . time taken to pass the men = 110 / 10 = 11 sec . answer : d"
