A train moves fast a telegraph post and a bridge 264 m long in 8 sec and 26 sec respectively. What is the speed of the train?	Choose the correct choice from the following answers:
A) 89  B) 23  C) 52.8  D) 79.2  E) 67
Let the length of the train be x m and its speed be y m/sec.   Then, x/y = 8 =&gt; x = 8y   (x + 264)/26 = y   y = 14.67   Speed = 14.67 m/sec = 14.67 * 18/5 = 52.8 km/hr.   Answer: Option 52.8
