A boy makes a diagram of a plane to a scale 1/400 of the actual size. If the diagram of the plane is 9.6 inches in length. What is the length, in feet, of the plane?
ایک لڑکا اصل سائز کے 1/400 پیمانے پر ہوائی جہاز کا خاکہ بناتا ہے۔ اگر ہوائی جہاز کے خاکے کی لمبائی 9.6 انچ ہے۔ ہوائی جہاز کی لمبائی، پاؤں میں، کیا ہے؟
Answer: 320
Explanation
The plane will be 400 times smaller than the real on paper.
length of plane on paper=9.6 inches
length of the plane in real=9.6*400 inches=3840
1 feet=12inches
length of the plane in real in feet=3840/12
=320 feet
