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

To obtain the value of 20% higher than 25, you need to multiply 25 by 20% (0.2) to get 5, then add 5 to 25. This gives a wind speed of 30 km/h at a height of 120 m. This is because 20% of 25 is equal to 5, so adding 5 to 25 results in a 20% increase. This is due to the wind speed increasing with height due to reduced friction and obstacles. So, to fly a kite sail at a height of 120 m, you should expect a wind speed of 30 km/h. Keep this in mind when setting up your kite sail and make sure to secure it properly at this height.
