Time, Speed and Distance questions with solutions
A train 250 m long is running at 90 km/h. How much time will it take to cross a pole?
- (A)20 seconds
- (B)3 seconds
- (C)7 seconds
- (D)10 seconds
Show answer and explanation
Correct answer: (D) 10 seconds
Convert the speed to metres per second: 90 × 5/18 = 25 m/s. To cross a pole the train covers its own length, so time = 250 ÷ 25 = 10 seconds.
Shortcut: km/h × 5/18 = m/s; time = length ÷ speed.
A train 360 m long is running at 72 km/h. How much time will it take to cross a pole?
- (A)18 seconds
- (B)15 seconds
- (C)5 seconds
- (D)36 seconds
Show answer and explanation
Correct answer: (A) 18 seconds
Convert the speed to metres per second: 72 × 5/18 = 20 m/s. To cross a pole the train covers its own length, so time = 360 ÷ 20 = 18 seconds.
Shortcut: km/h × 5/18 = m/s; time = length ÷ speed.
A train 360 m long is running at 72 km/h. How much time will it take to cross a pole?
- (A)5 seconds
- (B)22 seconds
- (C)36 seconds
- (D)18 seconds
Show answer and explanation
Correct answer: (D) 18 seconds
Convert the speed to metres per second: 72 × 5/18 = 20 m/s. To cross a pole the train covers its own length, so time = 360 ÷ 20 = 18 seconds.
Shortcut: km/h × 5/18 = m/s; time = length ÷ speed.
A train 130 m long is running at 36 km/h. How much time will it take to cross a pole?
- (A)17 seconds
- (B)26 seconds
- (C)10 seconds
- (D)13 seconds
Show answer and explanation
Correct answer: (D) 13 seconds
Convert the speed to metres per second: 36 × 5/18 = 10 m/s. To cross a pole the train covers its own length, so time = 130 ÷ 10 = 13 seconds.
Shortcut: km/h × 5/18 = m/s; time = length ÷ speed.
A train 500 m long is running at 90 km/h. How much time will it take to cross a pole?
- (A)17 seconds
- (B)40 seconds
- (C)24 seconds
- (D)20 seconds
Show answer and explanation
Correct answer: (D) 20 seconds
Convert the speed to metres per second: 90 × 5/18 = 25 m/s. To cross a pole the train covers its own length, so time = 500 ÷ 25 = 20 seconds.
Shortcut: km/h × 5/18 = m/s; time = length ÷ speed.
A train 330 m long is running at 54 km/h. How much time will it take to cross a pole?
- (A)19 seconds
- (B)44 seconds
- (C)26 seconds
- (D)22 seconds
Show answer and explanation
Correct answer: (D) 22 seconds
Convert the speed to metres per second: 54 × 5/18 = 15 m/s. To cross a pole the train covers its own length, so time = 330 ÷ 15 = 22 seconds.
Shortcut: km/h × 5/18 = m/s; time = length ÷ speed.
