Latest Train Crossing a Stationary Object MCQ Objective Questions
Train Crossing a Stationary Object Question 1:
A train passes a bridge in 18 seconds and a man standing on the bridge in 10 seconds. If the speed of the train is 90 km/hr, what is the length of the bridge ?
Answer (Detailed Solution Below)
Train Crossing a Stationary Object Question 1 Detailed Solution
Given:
Speed of the train = 90 km/hr = (90 × 1000) / 3600 = 25 m/s
Time taken to pass the man = 10 seconds
Time taken to pass the bridge = 18 seconds
Formula Used:
Total Length of Train + Length of Bridge = Speed × Time to pass the bridge
Length of Train = Speed × Time to pass the man
Calculation:
Length of Train = Speed × Time to pass the man
⇒ Length of Train = 25 × 10
⇒ Length of Train = 250 m
Total Length of Train + Length of Bridge = Speed × Time to pass the bridge
⇒ 250 + Length of Bridge = 25 × 18
⇒ 250 + Length of Bridge = 450
⇒ Length of Bridge = 450 - 250
⇒ Length of Bridge = 200 m
The length of the bridge is 200 m.
Train Crossing a Stationary Object Question 2:
A train 900 m long is running at 108 km/h. How long will it take to clear a 900 m long platform completely?
Answer (Detailed Solution Below)
Train Crossing a Stationary Object Question 2 Detailed Solution
Given:
Speed of train = 108 km/hr
Length of train = 900 meters
Length of platform = 900 meters
Formula Used:
Time = Distance/Speed
Calculation:
Speed of train in km/hr = 108 km/hr
Speed of train in m/sec = 108 × 5/18
⇒ 30 m/sec
Time taken by train to cross the platform:
As we know,
Time = Distance/Speed
⇒ (900 + 900)/30
⇒ 1800/30
⇒ 60 sec
∴ The train will cross the platform in 60 seconds.

Train Crossing a Stationary Object Question 7:
With a speed of 60km/hour a train crosses a bridge of 200 meters in 30 seconds. The length of train is
Answer (Detailed Solution Below)
Train Crossing a Stationary Object Question 7 Detailed Solution
Given:
Speed of the train = 60 km/hour.
Length of the bridge = 200 meters.
Time taken to cross the bridge = 30 seconds.
Formula Used:
Distance = Speed × Time
Calculation:
Convert speed from km/hour to m/s:
Speed = 60 km/hour = 60 × 1000 / 3600 = 50/3 m/s
Total distance covered in 30 seconds:
Distance = Speed × Time
Distance = (50/3) × 30
Distance = 500 meters
Length of the train = Total distance - Length of the bridge
Length of the train = 500 - 200
Length of the train = 300 meters
The length of the train is 300 meters.
