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}.
To find out how much more time it will take for the scuba diver to reach her goal depth of 50 feet, we can first calculate the rate at which she is descending.
Given that her elevation decreases by 2 feet in 8 seconds, we can determine her rate of descent by dividing the change in elevation by the change in time:
Rate of descent = Change in elevation / Change in time
In this case, the change in elevation is 2 feet and the change in time is 8 seconds, so:
Rate of descent = 2 feet / 8 seconds = 0.25 feet per second
To determine how many more seconds it will take for the scuba diver to reach a depth of 50 feet, we can calculate the difference between her current depth (20 feet below sea level) and her goal depth (50 feet below sea level). Then, we divide this difference by the rate of descent:
Difference in depth = 50 feet - 20 feet = 30 feet
Time required = Difference in depth / Rate of descent
Time required = 30 feet / 0.25 feet per second = 120 seconds
Therefore, the scuba diver will need an additional 120 seconds to reach her goal depth of 50 feet.
To find out how much more time it will take for the scuba diver to reach her goal depth of 50 feet, we need to determine the change in elevation per second. From the given information, we know that the elevation change in 8 seconds is 20 - 18 = 2 feet.
So, the scuba diver descends at a rate of 2 feet per 8 seconds.
To calculate how many more seconds it will take to reach a depth of 50 feet, we can set up a proportion:
2 feet / 8 seconds = 50 feet / x seconds
Cross-multiplying, we get:
2x = 8 * 50
Simplifying the equation:
2x = 400
Dividing both sides by 2:
x = 400 / 2
Calculating:
x = 200
Therefore, it will take 200 more seconds for the scuba diver to reach her goal depth of 50 feet.
