    Speed in km/hr = speed in m/sec x (18 / 5 )
    Speed in km/hr = (22.5 x 18 /5 ) km/hr.

    Correct Option: B

    Speed in km/hr = speed in m/sec x (18 / 5 )
    Speed in km/hr = (22.5 x 18 /5 ) km/hr
    = 81 km/hr.


  1. A speed of 55 m / sec. is the same as ?
    1. 198 km/hr.
    2. 11 km/hr.
    3. 15 5/18 km/hr.
    4. 275 km/hr.

    Speed in km/hr = speed in m/sec x (18 / 5 )
    Speed in km/hr = (55 x 18 /5 ) km/hr

    Correct Option: A

    Speed in km/hr = speed in m/sec x (18 / 5 )
    Speed in km/hr = ( 55 x 18 /5 ) km/hr
    = 198 km/hr.



  1. A speed of 30.6 km/hr. is the same as ?
    1. 5.1 m/sec.
    2. 8.5 m/sec.
    3. 110.16 m/sec.
    4. 1.7 m/sec.

    Speed in m/sec = speed in km/hr x (5 / 18 )
    Speed in m/sec = ( 30.6 x 18 /5 ) m/sec

    Correct Option: B

    Speed in m/sec = speed in km/hr x (5 / 18 )
    Speed in m/sec = ( 30.6 x 18 /5 ) m/sec
    = 8.5 m/sec


  1. A speed of 36 km/hr. is the same as ?
    1. 10 m/sec.
    2. 7.2 m/sec.
    3. 2 m/sec.
    4. 129.6 m/sec.

    Speed in m/sec = speed in km/hr x (5 / 18 )
    Speed in m/sec = ( 36 x 5/18 ) m/sec

    Correct Option: A

    Speed in m/sec = speed in km/hr x (5 / 18 )
    Speed in m/sec = ( 36 x 5/18 ) m/sec
    = 10 m/sec



  1. Suresh started cycling along the boundaries of a square field from corner point A. After half an hour, he reached the corner point C, diagonally opposite to A, if his speed was 8km/hr , what is the area of the field in square km.?
    1. 64
    2. 8
    3. 4
    4. Cannot be determined

    Length of two sides of square
    = 8 x 1/2 km.
    = 4 km.

    Correct Option: C

    Length of two sides of square
    = 8 x 1/2 km.
    = 4 km.

    ∴ Area of the field = 2 x 2 sq. km
    = 4 sq. km.
