    Answer: 2.5x10^8 kilometers

    Explanation:

    Given that:

    Distance between the earth and the sun = 2.5x10¹¹metres

    Convert distance in metres to kilometers

    Recall that 1000 metres = 1 kilometers

    So, 2.5x10¹¹metres = Z kilometers

    To get the value of Z, cross multiply

    Z km x 1000 m = (2.5x10¹¹metres x 1km)

    1000Z = 2.5 x 10^11

    Divide both sides by Z

    1000Z/1000 = 2.5 x 10^11/1000

    Z = 2.5x10^8km

    Thus, the distance between the earth and the sun is about 2.5x10^8km
