What is the speed of the train in km/hr whose length is 360 metres which passes a pole in 18 seconds? Choose the correct choice from the following answers: A) 59/9 km/hr B) 50/9 km/hr C) 25/6 km/hr D) 55/18 km/hr E) 60/18 km/hr
Speed=(18x5/18)=5 m/sec.   Length of the train= 360 metre   Time=18s   Speed=length / time   Speed=(360/8)=20 m/sec = 20*5/18 km/hr = 50/9 km/hr   Answer: 50/9 km/hr
