    A train 150 m long is running at 72 km / hr. It crosses a bridge in 13 sec. Find the length of the bridge.

    Question A train 150 m long is running at 72

    km/hr. It crosses a bridge in

    13

    sec. Find the length of the bridge.

    Open in App Solution Speed of the train = 72 km/hr = 72 × 1000 3600 m/sec = 72 × 5 18 m/sec = 20 m/sec

    Time taken to cross the bridge

    = 13 sec

    Therefore, total distance covered by the train

    = 20 × 13 = 260 m

    Therefore, length of the bridge

    = 260 − 150 = 110 m Suggest Corrections 42

    Given:

    Length of train = 240m

    Speed of train = 60kmph = 60 × 5/18 = 50/3 m/s

    Length of the platform = 260 m

    Concept Used:

    Time taken to cross a platform = (length of train + length of the platform)/speed of the train

    Calculation:

    Time required = (240 + 260)/(50/3) = 500/(50/3)

    ⇒ Time = 30 seconds

    ∴ In 30 seconds the train will cross the platform of length 260m.

    Originally Answered: A train running at a speed of 72 km/hr crossed a 260 meter platform in 23 sec, Find length of the train?

    The train crossing the platform means that

    At the time the timer is started, the train’s front most part is at the starting of the platform.

    At the time the timer is stopped, i.e, 23 seconds later, the train’s rear most part is at the end of the platform.

    This means that in 23 seconds, the train has traveled a distance equal to the length of the platform + the length of the train.

    72 km/h = 20 m/s. In 23 seconds at this speed, the train travels 20 x 23 = 460 meters.

    Length of platform + length if train = 460m.

    Length of train = 460 - length of platform = 460–260 = 200m.

    To cross the bridge the distance to be travelled= Length of train + Platform

    =( L + 260), where L= length of the train.

    Speed of the train= 72- Km= 72 x 5/18 =20- m/ sec.

    Distance travelled in 23- seconds= 20 x 23= 460- metres.

    So Length of the train= 460- 260

    = 200- metres Shashank Shekhar

    A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?

    The train needs to cover a total distance D= length of itself + length of platform

    D= L+250

    Let L be length of train.

    D= Speed * time

    converting 72kmph in m/s we get 20m/s

    D= 20*26 D= 520m therefore L =270m

    72 km/h = 20 m/s

    (260 + L) / 23 = 20 m/s

    260 + L = 460 m

    Length of the train L = 200 m

    The speed of the train is 72Kmps

    In 60 Min it covers 72000 Mtrs

    in 1 Min it will cover 72000/60= 1200 Mtrs

    Or 1200 Mtrs in 60 Sec

    260 Mtrs = 60/1200*260= 13 Sec

    or In 13 Sec it covers 260 Mtr

    In 23 Sec it will cover 260/13*23 = 460 Mtr

    460 Mtr is length of Platform + length of train

    So length of the train will be 460–260= 200 Mtrs

    Answer 200 Mtrs (SOLVED)
