Question : 11 [SSC CGL Tier-I 2016]
A train 110 metre long is running with a speed of 60 kmph. In what time will it pass a man who is running at 6 kmph in the direction opposite to that in which the train is going ?
a) 6 seconds
b) 7 seconds
c) 10 seconds
d) 5 seconds
Answer »Answer: (a)
Relative speed of train
= (60 + 6) kmph.
=$({66 × 5}/18)$ m/sec.
= $55/3$ m/sec.
Length of train = 110 metre
∴ Required time = $(110/{55/3})$ seconds
= $({110 × 3}/55)$ seconds = 6 seconds
Question : 12 [SSC CPO S.I.2004]
A person standing on a railway platform noticed that a train took 21 seconds to completely pass through the platform which was 84 m long and it took 9 seconds in passing him. The speed of the train was
a) 32.4 km/hour
b) 50.4 km/hour
c) 75.6 km/hour
d) 25.2 km/hour
Answer »Answer: (d)
Rule 10 and Rule 1,
Let the length of train be x metres.
When the train crosses the standing man, its speed = $x/9$
When the train crosses the platform of length 84 m, its speed = ${x + 84}/21$
Obviously, $x/9 = {x + 84}/21$
21x - 9x = 9 × 84
12x = 9 × 84
$x = {9 × 84}/12$ = 63 m
Required speed
= $63/9$ m/sec = $63/9 × 18/5$ kmph
= 25.2 kmph
Question : 13 [SSC CGL Tier-I 2013]
A train moving at a rate of 36 km/hr. crosses a standing man in 10 seconds. It will cross a platform 55 metres long, in :
a) 7 seconds
b) 15$1/2$ seconds
c) 5$1/2$ seconds
d) 6 seconds
Answer »Answer: (b)
Rule 10 and Rule 1,
Speed of train = 36 kmph
= $36 × 5/18$ = 10 m/sec
Length of train
= 10 × 10 = 100 metres
Required time = ${100 + 55}/10$
= 15$5/10 = 15{1}/2$ second
= 15.5 seconds
Question : 14 [SSC CGL Prelim 2004]
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) 70 km/hr
b) 79 km/hr
c) 79.2 km/hr
d) 69.5 km/hr
Answer »Answer: (c)
Rule 10 and Rule 1,
Let the length of train be x metres.
Then, speed of train when it passes a telegraph post
= $x/8$ m/sec. and speed of train, when it passes the bridge = ${x + 264}/20$
Clearly, $x/8 = {x + 264}/20$
$x/2 = {x +264}/5$
5x = 2x + 528
3x = 528 ⇒ $x = 528/3$ = 176m
Speed of train
= $176/8$ = 22 m/sec.
= 22 × $18/5$ Kmph = 79.2 kmph
Question : 15 [SSC CPO S.I.2007]
A train passes a platform 90 metre long in 30 seconds and a man standing on the platform in 15 seconds. The speed of the train is :
a) 14.6 kmph
b) 18.4 kmph
c) 21.6 kmph
d) 12.4 kmph
Answer »Answer: (c)
Rule 10 and Rule 1,
Let the length of the train be x
According to the question,
Speed of the train
= ${x + 90}/30 = 15$
x + 90 = 2x ⇒ x = 90 m
Speed of train = $90/15$
= 6 m/s = $6 × 18/5$ kmph
= 21.6 kmph
