    Avg Speed = (16 - 0) / (1 - 0) = 16 ft/sec

    16 ft/sec x (60 sec / 1 min) = 960 ft/min

    16 feet per second was her average speed DURING the 1st second.

    On the other hand, her instantaneous speed at the end of the 1st second is around 32 ft/sec, but I don't think that's what they're after.
