# What is the Speed of Train

A train 132m long passes a telegraph post in 6 seconds. The speed of the train is:

- 70 km/hr
- 72 km/hr
- 79.2 km/hr
- 80 km/hr

**Answer:(3) 79.2 km/hr.**

A train covered distance = 132m

Taken time = 6 sec.

Speed of train = 132/6

22 m/sec.

Speed in Km/hr = 22 x 60 x 60/1000

= **79.2 Km/hr Ans.**

Hence, the speed of train is 79.2 km/hr.
