Q8. One advantage of using a kite sail 2 points
is that it flies at a height of 150 m.
There, the wind speed is
approximately 25% higher than down
on the deck of the ship. At what
approximate speed does the wind
blow into a kite sail when a wind speed
of 24 km/h is measured on the deck of
the ship? (पतंग शीड वापरण्याचा एक फायदा
म्हणजे ते 150 मी उंचीवर असते. जहाजाच्या
डेकवरील वाऱ्याच्या गतीच्या तुलनेत 150 मी
उंचीवर वाऱ्याची गती 25% अधिक असते.
जहाजाच्या डेकवरील वाऱ्याची गती 24 किमी/तास
असेल तर पतंग शिडाच्या टोकावर वाऱ्याची गती
किती असेल?)
O 6 km/h (6 किमी/तास)
O 18 km/h (18 किमी/तास)
O 25 km/h (25 किमी/तास)
O 30 km/h (30 किमी/तास)
Answers
Answer:
25 km/hr
Step-by-step explanation:
this is ur answer
Given : kite sail flies at a height of 150 m. There the wind speed is
approximately 25% higher than down on the deck of the ship
a wind speed of 24 km/h is measured on the deck of the ship
To Find : approximate speed does the wind blow into a kite sail
Solution:
Speed at deck = 24 km/hr
Speed kite sail is approximate 25% higher
Hence
approximate speed the wind blow into a kite sail = 24 + (25/100)24
= 24 + 24/4
= 24 + 6
= 30 km/hr
approximate speed the wind blow into a kite sail = 30 km/hr
