    B.

    Step-by-step explanation:

    2 kilometer = 5 cm

    And

    5 km = ? cm

    Using unitary method

    2 km = 5 cm

    1 km = 5/2 cm

    1 km = 2.5 cm

    Now

    Multiplying both sides by 5 we'll get:

    5 km = 2.5 * 5 cm

    5 km = 12.5 cm

    Given that 5 centimeters equals 2 kilometers, we are asked to find how many centimeters equals to 5 kilometers.

    So, we know the rate is 5 centimeters is equal to 2 kilometers.

    We should find out how many centimeters equals 1 kilometer.

    To do this, we can divide 5 centimeters by 2 to find out how many centimeters is 1 kilometer.

    5/2 = 2.5

    So, the new rate is 2.5cm = 1km.

    Then, all we need to do is multiply the new rate by 5 to find out how many centimeters is 5 kilometers.

    5 x 2.5 = 12.5

    Therefore, 12.5 centimeters equals a distance of 5 kilometers.
