Question : 1
A train is 250m long. If the train takes 50 seconds to cross a tree by the railway line, then the speed of the train in km/hr is :
a) 9
b) 5
c) 18
d) 10
Answer »Answer: (c)
Using Rule 1,
Speed of train = $\text"Length of train"/ \text"Time taken in crossing"$
= $250/50$ = 5 m/sec.
= $(5 × 18/5)$ kmph = 18 kmph
Question : 2
How many seconds will a 500 metre long train take to cross a man walking with a speed of 3 km/hr. in the direction of the moving train if the speed of the train is 63 km/hr ?
a) 30 sec
b) 40 sec
c) 45 sec
d) 25 sec
Answer »Answer: (a)
Using Rule 5,
Relative speed of train
= 63–3 = 60 kmph
= $60 × 5/18$ m / sec
Time = $\text"Length of train"/ \text"Relative Speed"$
= ${500 × 18}/{60 × 5}$ = 30 sec.
Question : 3
A train 100m long is running at the speed of 30 km/hr. The time (in second) in which it will pass a man standing near the railway line is :
a) 11
b) 12
c) 15
d) 10
Answer »Answer: (b)
Using Rule 1,
If a train crosses an electric pole, a sitting/standing man, km or milestone etc. then distance = Length of the train.
Then, Length of train = Speed × Time And Time = $\text"Length of train"/\text"Speed"$
and Speed = $\text"Length of train"/\text"Time"$
In this situation, the train covers it length.
Required time = $100/{30 × 1000}$ hr.
= ${100 × 60 × 60}/{30 × 1000}$ = 12 seconds
Question : 4
A train 300 m long is running with a speed of 54 km/hr. In what time will it cross a telephone pole?
a) 15 seconds
b) 17 seconds
c) 18 seconds
d) 20 seconds
Answer »Answer: (d)
Using Rule 1,
Speed of train = 54 kmph
= $({54 × 5}/18)$ m/sec = 15 m/sec
Required time = $\text"Length of trains"/ \text"Speedof train"$
= $300/15$ = 20 seconds
Question : 5
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
Question : 6
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.
