Problems on Trains - General Aptitude

Q1:

A train moves past a telegraph post and a bridge 264 m long in 8 seconds and 20 seconds respectively. What is the speed of the train?

A 69.5 km/hr

B 70 km/hr

C 79 km/hr

D 79.2 km/hr

ANS:A - 69.5 km/hr

Then, x = 8     =>     x = 8y
y
Now, x + 264 = y
20
=> 8y + 264 = 20y => y = 22.
Therefore Speed = 22 m/sec = ( 22 x 18 ( km/hr = 79.2 km/hr.
