Answer: - 33

Step-by-step explanation:

Since, the speed of scuba diver = 2.5 feet per second

Thus, the distance covered by her in 7 second = 2.5 × 7 = 17.5 feet

But, According to the question,

She is 15.5 feet below the surface of water when she start swimming.

Thus, her total distance from the surface of water after 7 second

= Her distance from the surface when she start + the distance cover by her in 7 second

= 15.5 + 17.5 = 33 feet.

Thus, -33 represents her location relative to the surface after 7 seconds when we take surface as x-axis.

2.5 × 7 = 17.5

15.5 + 17.5 = 33

The scuba diver is -33 feet below the surface of water after 7 seconds.
