A parasail is 120 of a meter above the water. Then, after 10 minutes, the parasail is 150 of a meter above the water. What is the change in height?
To find the change in height, we subtract the initial height from the final height.
Final height - Initial height = Change in height
The initial height of the parasail is 120 meters above the water, and the final height is 150 meters above the water.
So, the change in height is: 150 meters - 120 meters = 30 meters.
Therefore, the change in height is 30 meters.
