    Each miner was 672 meters below the surface.

    Step-by-step explanation:

    The speed of the shuttle = 70 cm/s

    Time taken to get each miner out = 16 minutes

    Converting 16 minutes into seconds, we get

    the total time taken by shuttle to reach the miner = 16 x 60s = 960 s

    So, Total Distance traveled by shuttle = Speed of the shuttle X Total time taken

    or, Total distance = 70 cm/s x 960 s = 67,200 cm

    As, 100 cm = 1 meter

    ⇒67,200 cm = (67,200 / 100) meters = 672 m

    or, D = 672 m

    Hence, each miner was 672 meters below the surface.
