A whale was diving at a rate of 2 meters per second. How long will it take for the whale to
get from the surface of the ocean to an elevation of -12 meters at that rate?
B.
A swimmer dove below the surface of the ocean. After 2 minutes, she was 12 meters below
the surface. At what rate was she diving?
C.
The temperature was -12 degrees Celsius and rose to 2 degrees Celsius. What was the
change in temperature?
D.
The temperature was 2 degrees Celsius and fell to -12 degrees Celsius. What was the

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
