  1. A train 240 m long passes a bridge 120 m long in 24 sec. Find the speed with which the train in moving ?








  1. View Hint View Answer Discuss in Forum

    Required speed = (240 + 120) / 24 = 15 m/sec
    = 15 x (18/5) km/hr = 54 km/hr

    Correct Option: B

    Required speed = (240 + 120) / 24 = 15 m/sec
    = 15 x (18/5) km/hr = 54 km/hr

  1. A train 110 metres long travels at 60 km/hr. How long does it take to cross a telegraph post ?








  1. View Hint View Answer Discuss in Forum

    Time = distance / speed

    Correct Option: C

    Time = distance / speed
    =110 / {60 x 18/5} = 6.6 sec.

  1. A train 550 metres long is running with a speed of 55 km per hour. In what time will it pass a signal post ?








  1. View Hint View Answer Discuss in Forum

    Distance covered = 550 meter. = 0.55 km
    Speed of the train = 55 km/hr

    Correct Option: D

    Distance covered = 550 meter. = 0.55 km
    Speed of the train = 55 km/hr

    So time taken = 0.55 / 55 =1/100 hr = (60 x 60 )/100 sec = 36 sec

  1. A train 135 metres long is running with a speed of 54 km per hour. In what time will it pass a telegraph post ?








  1. View Hint View Answer Discuss in Forum

    Distance traveled = length of the train = 135 m
    Speed of the train = 54 Km/hr = 54 x 5/18 = 15 m/s.

    Correct Option: A

    Distance traveled = length of the train = 135 m
    Speed of the train = 54 Km/hr = 54 x 5/18 = 15 m/s.

    Time taken by train = 135 / 15 sec. = 9 sec.

  1. A train 110 metres in length runs through a station at the rate of 36 km per hour. How long will it take to pass a given point ?








  1. View Hint View Answer Discuss in Forum

    Speed of the train = 36 km/hr = 36 x (5/18) = 10 m/sec
    ∴ Required time = 110/10 = 11 sec

    Correct Option: A

    Speed of the train = 36 km/hr = 36 x (5/18) = 10 m/sec
    ∴ Required time = 110/10 = 11 sec
