A dolphin is fitted with a GPS system that monitors its position in relationship to a research ship. The table below contains the time (in seconds) after the dolphin is released from the ship and the distance (in feet) the dolphin is from the research ship. Based on the table, do you think the data follow a linear pattern? Explain your answer.

Find the equation that best fits the data.

Estimate how far the dolphin will be from the ship after 160 seconds? Explain how you made your estimate.
