Question
A scuba diver is diving at a. Constant rate when her team on the surface requests a status update. She looks at her watch which says her elevation os 18 feet below sea level. 8 seconds later, her elevation is 20 feet below sea level? How much more seconds until she reach her goal depth of 50 feet?

The scuba diver is descending at a constant rate. In 8 seconds, her elevation decreases by 20 - 18 = <<20-18=2>>2 feet.
Therefore, her rate of descent is 2 feet / 8 seconds = <<2/8=0.25>>0.25 feet per second.
To reach her goal depth of 50 feet, she needs to descend an additional 50 - 18 = <<50-18=32>>32 feet.
To calculate the time in seconds to reach this depth, we can use the formula: time = distance / rate.
The time to descend the remaining distance is 32 feet / 0.25 feet per second = <<32/0.25=128>>128 seconds.
Therefore, she needs an additional 128 - 8 = <<128-8=120>>120 seconds to reach her goal depth. Answer: \boxed{120}.
Therefore, her rate of descent is 2 feet / 8 seconds = <<2/8=0.25>>0.25 feet per second.
To reach her goal depth of 50 feet, she needs to descend an additional 50 - 18 = <<50-18=32>>32 feet.
