Question : 16 [SSC CHSL 2012]
A train 100 metres long meets a man going in opposite direction at 5 km/hr and passes him in 7$1/5$ seconds. What is the speed of the train (in km/hr) ?
a) 60 km/hr
b) 55 km/hr
c) 50 km/hr
d) 45 km/hr
Answer »Answer: (d)
Using Rule 6,
Let speed of train be x kmph
Relative speed = (x + 5) kmph
Length of train
= $100/1000$ km = $1/10$ km
${1/10}/{x + 5} = 36/{5 × 60 × 60}$
$1/{10(x + 5)} = 1/500$
x + 5 = 50 ⇒ x = 45 kmph
Question : 17 [SSC CHSL 2015]
A train 150m long passes a km stone in 30 seconds and another train of the same length travelling in opposite direction in 10 seconds. The speed ot the second train is :
a) 125 km/hr
b) 25 km/hr
c) 75 km/hr
d) 90 km/hr
Answer »Answer: (d)
Speed of train A
= $150/30$ = 5 m/sec.
Speed of train B = x m/sec.
Relative speed = (5+x) m/sec.
Length of both trains
= Relative speed × Time
300 = (5 + x) × 10
5 + x = $300/10$ = 30
x = 30 - 5 = 25 m/sec.
= $({25 × 18}/5)$ kmph. = 90 kmph.
Question : 18 [SSC CGL Tier-I 2016]
A train 100 metre long is running at a speed of 120 km/hr. The time taken to pass a person standing near the line is
a) 3 seconds
b) 5 seconds
c) 7 seconds
d) 1 second
Answer »Answer: (a)
Speed of train = 120 kmph.
= $({120 × 5}/18)$ m./sec. = $100/3$ m./sec.
Required time = $\text"Length of train"/ \text"Speed of train"$
= $(100/{100/3})$ seconds
= $(100/100 × 3)$ seconds = 3 seconds
Question : 19 [SSC CGL Tier-I 2016]
A train 240 metres in length crosses a telegraph post in 16 seconds. The speed of the train is
a) 52 km/hr
b) 54 km/hr
c) 56 km/hr
d) 50 km/hr
Answer »Answer: (b)
When a train crosses a pole it travels a distance equal to its length.
Speed of train
= $240/16$ = 15 m./sec.
= $(15 × 18/5)$ kmph = 54 kmph.
Question : 20 [SSC CGL Prelim 2002]
A train is 125 m long. If the train takes 30 seconds to cross a tree by the railway line, then the speed of the train is :
a) 15 km/hr
b) 16 km/hr
c) 12 km/hr
d) 14 km/hr
Answer »Answer: (a)
Using Rule 1,
Speed = $\text"Distance"/ \text"Time"$
=$125/30$ = 41.6 m/s
4.16 m/s = 4.16 × $18/5$ = 15 km/hr
