Question - 1:Two trains, each 100 m long, moving in opposite directions, cross each other in 8 seconds. If one is moving twice as fast the other, then the speed of the faster train is:?

1. 30 km/hr
2. 45 km/hr
3. 60 km/hr
4. 75 km/hr

Show/Hide Answer

Answer = C - 60 km/hr
Explanation: NO Explanation

Question - 2:Two goods train each 500 m long, arc running in opposite directions on parallel tracks. Their speeds are 45 km /hr and 30 km/hr respectively Find the time taken by the slower train to pass the driver of the faster one.?

1. 12 sec
2. 24 sec
3. 48 sec
4. 60 sec

Show/Hide Answer

Answer = C - 48 sec
Explanation: Relative speed = (45 + 30 )km/hr
= (75 x 5/18)m/sec
=(125 / 6) m/sec
Total Distance covered = (500 + 500) m
= 1000 m
Required time = (1000 x 6 /125)sec
= 48 sec

Question - 3:A train 110 m long passes a man, running at 6 kmph in the direction opposite to that of the train, in 6 seconds The speed of the train is - ?

1. 54 km/hr
2. 60 km/hr
3. 66 km/hr
4. 72 km/hr

Show/Hide Answer

Answer = B - 60 km/hr
Explanation: Speed of the train relative to man =(110 / 6 ) m/sec

= (110 / 6 x 18 /5) km/hr
= 66 km/hr

Speed of the train be x kmph

Relative Speed =(x + 6 ) kmph.

= x + 6 = 66

x = 60.

Question - 4:A 270 metres long train running at the speed of 120 kmph crosses another train running in opposite direction at the speed of 80 kmph in 9 seconds. What is the Length of the other train ? ?

1. 230 m
2. 240 m
3. 260 m
4. 320 m

Show/Hide Answer

Answer = A - 230 m
Explanation: Relative Speed = (120 + 80)km/hr
= (200 x 5/18)m/sec
= (500 / 9)m/sec
Let the length of the other train be x metres
Then, x + 270 / 9
x + 270 = 500
x = 230.

Question - 5:A train speeds past a pole in 15 seconds and a platform 100 m long in 25 seconds. Its
length is: ?

1. 50 m
2. 150 m
3. 200 m
4. Data inadequate

Show/Hide Answer

Answer = B - 150 m
Explanation: NO Explanation

Question - 6:Two trains 140 m and 160 m long run at the speed of 60 km/hr and 40 km/hr respectively in opposite directions on parallel tracks. The time (in seconds) which they take to cross each other, is: ?

1. 9
2. 9.6
3. 10
4. 10.8

Show/Hide Answer

Answer = D - 10.8
Explanation: NO Explanation

Question - 7:Two trains travel in opposite directions at 36 kmph and 45 kmph and a man sitting in slower train passes the faster train in 8 seconds. The length of the faster train is ?

1. 80 m
2. 100 m
3. 120 m
4. 180 m

Show/Hide Answer

Answer = D - 180 m
Explanation: Relative speed = (36 + 45) km/hr
= (81 x 5/18) m/sec
= (45 / 2) m/sec
Length of the train = (45 / 2 x 8) m
= 180 m.

Question - 8: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? ?

1. 69.5 km/hr
2. 70 km/hr
3. 79 km/hr
4. 79.2 km/hr

Show/Hide Answer

Answer = D - 79.2 km/hr
Explanation: NO Explanation
