To determine the change in height of the parasail, we can subtract the initial height from the final height.
Initial height: \( \frac{1}{120} \) meters
Final height: \( \frac{1}{150} \) meters
To perform the subtraction, we first need a common denominator. The least common multiple of 120 and 150 is 600.
Now, let's convert both fractions to have a denominator of 600:
-
For \( \frac{1}{120} \): \[ \frac{1}{120} = \frac{5}{600} \]
-
For \( \frac{1}{150} \): \[ \frac{1}{150} = \frac{4}{600} \]
Now we can find the change in height:
\[ \text{Change in height} = \frac{4}{600} - \frac{5}{600} = \frac{4 - 5}{600} = \frac{-1}{600} \]
This means that the change in height is \( -\frac{1}{600} \) meters, indicating that the parasail actually descended by \( \frac{1}{600} \) meters.
