Question : 11 [SSC CGL Prelim 2002
A 120 m long train takes 10 seconds to cross a man standing on a platform. What is the speed of the train ?
a) 10 m/sec.
b) 15 m/sec.
c) 20 m/sec.
d) 12 m/sec.
Answer »Answer: (d)
Using Rule 1,
In crossing a man standing on platform, train crosses its own length.
Speed of train = $120/10 = 12$m/s
Question : 12 [SSC CGL Tier-I 2015]
A train 180 metres long is running at a speed of 90 km/h. How long will it take to pass a post ?
a) 7.8 secs
b) 8 secs
c) 7.2 secs
d) 8.2 secs
Answer »Answer: (c)
Using Rule 1,
Speed of train = 90 kmph
= $(90 × 5/18)$ m/sec. = 25 m/sec.
When a train crosses a post, it covers a distance equal to its own length.
Required time = $\text"Distance"/ \text"Speed"$
= $180/25$ = 7.2 seconds
Question : 13 [SSC CGL Tier-I 2016]
In what time will a train, 60 metre long, running at the rate of 36 km/hr pass a telegraph post ?
a) 8 seconds
b) 7 seconds
c) 6 seconds
d) 9 seconds
Answer »Answer: (c)
Speed of train = 36 kmph
= $({36 × 5}/18)$ m./sec. = 10 m./sec.
Required time = $\text"Length of train"/ \text"Speed of train"$
= $60/10$ = 6 seconds
Question : 14 [SSC CPO S.I.2006]
A train passes two persons walking in the same direction at a speed of 3 km/hour and 5km/ hour respectively in 10 seconds and 11 seconds respectively. The speed of the train is
a) 27 km/hour
b) 25 km/hour
c) 24 km/hour
d) 28 km/hour
Answer »Answer: (b)
Let the speed of train be x kmph
and its length be y km.
When the train crosses a man, it covers its own length
According to he question,
$y/{(x - 3) × 5/18}$ = 10
18y = 10 × 5(x –3)
18y = 50x –150 ..... (i)
and, $y/{(x - 5) × 5/18}$ = 11
18y = 55(x–5)
18y = 55x –275 .... (ii)
From equations (i) and (ii),
55x –275 = 50x–150
55x –50x = 275 - 150
5x = 125 ⇒ x = $125/5$ = 25
Speed of the train = 25 kmph
Using Rule 7,A train crosses two men in $t_1$ seconds and $t_2$ seconds running in the same direction with the speed $s_1$ and $s_2$ then the speed of train is = ${t_1S_1 - t_2S_2}/{t_1 - t_2}$and length of train is l = $(S_1 - S_2)({t_1 - t_2}/{t_1 - t_2})$
Here, $S_1 = 3, S_2 = 5, t_1 = 10/3600 , t_2 = 11/3600$
Speed of train = ${t_1S_1 - t_2S_2}/{t_1 - t_2}$
= ${{3 × 10}/3600 - {5 × 11}/3600}/{10/3600 - 11/3600}$
= ${-25}/3600 × 3600/{- 1}$ = 25 m/sec
Question : 15 [SSC Investigator 2010]
A train is running at 36 km/hr. If it crosses a pole in 25 seconds, its length is
a) 250 m
b) 255 m
c) 260 m
d) 248 m
Answer »Answer: (a)
Using Rule 1,
Speed of train = 36 kmph
= $({36 × 5}/18)$ m/sec = 10 m/sec.
Length of train = Speed × time
= 10 × 25 = 250 metre
