A wind speed of
25
25 km/h is measured on the deck of the ship. A kite sail can fly at a height of
120
120 m. At that height, the wind speed is approximately
20
%
20% higher than down on the deck of the ship.
After finding the value of
20

20% of
25
25, which operation has to be performed to obtain the value of

To obtain the value of 20% higher than 25km/h, we first need to find 20% of 25. To do this, we multiply 25 by 20% or 0.2. This gives us a value of 5km/h. This means that at 120m above the deck of the ship, the wind speed will be 5km/h higher, making it 30km/h. Therefore, the operation we need to perform to obtain the value of 20% higher than 25km/h is to add 5km/h to 25km/h. This will give us the final value of 30km/h at a height of 120m. It is important to note that wind speeds can vary and may not always be exactly 20% higher at a certain height. However, this is a general guideline that can be used when estimating wind speed at different heights.
