A train moves past a house and a river bridge 264 m long in 8 seconds and 20 seconds respectively. What is the speed of the train ?
Options
A) 79.2 km/hr	B) 60.5 km/hr	C) 65 km/hr	D) 62.5 km/hr	E) 75.2 km/hr
length of the train be p metres and its speed - q m/sec.   p/q = 8 =&gt; p = 8q   p+264/20 = q   8q+264 = 20q   q = 22   speed = 22 m/s = (22*18/5)=
