Match each situation to one of the equations. 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?

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?

The temperature was - 12 degrees Celsius
and rose to 2 degrees Celsius. What was the
change in temperature?

The temperature was 2 degrees Celsius and
fell to -12 degrees Celsius. What was the
change in temperature?
