Same/Opposite Direction Question 1:
Train A travels at a speed of 90 km/h and takes 9 seconds to pass a Man. It meets Train B, which is moving in the opposite direction at 72 km/h and length of the train B is x m. If Train A crosses Train B completely in 9 seconds. Find the value of 2x?
Answer (Detailed Solution Below)
Same/Opposite Direction Question 1 Detailed Solution
Given:
Speed of Train A = 90 km/h
Speed of Train B = 72 km/h
Train A crosses a man in 9 sec
Train A crosses Train B in 9 sec
Formula used:
Speed in m/s = (Speed in km/h) × 5/18
Length = Speed × Time
Calculations:
Train A speed = 90 × 5/18 = 25 m/s
⇒ Length of Train A = 25 × 9 = 225 m
Relative speed = (90 + 72) × 5/18 = 162 × 5/18 = 45 m/s
Total length = 45 × 9 = 405 m
Length of Train B = 405 - 225 = 180 m
⇒ x = 180 ⇒ 2x = 360
∴ The value of 2x is 360.
Same/Opposite Direction Question 2:
Two trains of lengths 125 m and 175 m respectively are running in the same direction at 40 km/h and 22 km/h respectively. How much time will they take to pass each other completely?
Answer (Detailed Solution Below)
Same/Opposite Direction Question 2 Detailed Solution
Given:
Length of first train = 125 m
Length of second train = 175 m
Speed of first train = 40 km/h
Speed of second train = 22 km/h
Formula Used:
Time taken to pass each other completely = Total distance / Relative speed
Calculation:
Total distance = Length of first train + Length of second train
Total distance = 125 m + 175 m
Total distance = 300 m
Relative speed = Speed of first train - Speed of second train
Relative speed = 40 km/h - 22 km/h = 18 km/h
Convert relative speed into m/s:
Relative speed = 18 × (1000 / 3600) m/s
Relative speed = 5 m/s
Time taken to pass each other completely = Total distance / Relative speed
⇒ Time = 300 / 5
⇒ Time = 60 seconds = 1 min
The correct answer is option 2.

Same/Opposite Direction Question 3:
Two trains of lengths 125 m and 175 m respectively are running in the same direction at 40 km/h and 22 km/h respectively. How much time will they take to pass each other completely?
Answer (Detailed Solution Below)
Same/Opposite Direction Question 3 Detailed Solution
Given:
Length of first train = 125 m
Length of second train = 175 m
Speed of first train = 40 km/h
Speed of second train = 22 km/h
Formula Used:
Time taken to pass each other completely = Total distance / Relative speed
Calculation:
Total distance = Length of first train + Length of second train
Total distance = 125 m + 175 m
Total distance = 300 m
Relative speed = Speed of first train - Speed of second train
Relative speed = 40 km/h - 22 km/h = 18 km/h
Convert relative speed into m/s:
Relative speed = 18 × (1000 / 3600) m/s
Relative speed = 5 m/s
Time taken to pass each other completely = Total distance / Relative speed
⇒ Time = 300 / 5
⇒ Time = 60 seconds = 1 min
The correct answer is option 2.
Same/Opposite Direction Question 4:
Train A travels at a speed of 90 km/h and takes 9 seconds to pass a Man. It meets Train B, which is moving in the opposite direction at 72 km/h and length of the train B is x m. If Train A crosses Train B completely in 9 seconds. Find the value of 2x?
Answer (Detailed Solution Below)
Same/Opposite Direction Question 4 Detailed Solution
Given:
Speed of Train A = 90 km/h
Speed of Train B = 72 km/h
Train A crosses a man in 9 sec
Train A crosses Train B in 9 sec
Formula used:
Speed in m/s = (Speed in km/h) × 5/18
Length = Speed × Time
Calculations:
Train A speed = 90 × 5/18 = 25 m/s
⇒ Length of Train A = 25 × 9 = 225 m
Relative speed = (90 + 72) × 5/18 = 162 × 5/18 = 45 m/s
Total length = 45 × 9 = 405 m
Length of Train B = 405 - 225 = 180 m
⇒ x = 180 ⇒ 2x = 360
∴ The value of 2x is 360.
