A at duck is resting on the surface of a lake,
an altitude of 0 feet above sea level. It dives to
-5 feet to eat. Then it returns to the surface.
Which of these occurred between the time the
duck ate and the time it returned to the surface?
A. The duck's altitude increased by 5 feet.
B.
The duck's altitude decreased by 5 feet.
C. The duck's altitude increased by 10 feet.
D. The duck's altitude remained the same.
if the duck started at 0 its at ground level, it states that the duck dove, so minus 5 or -5, decreased means take away. Thus the answer is B. Sorry if I didn’t word this to help explain.
