Question

The ratio of the length of an airplane wing to its width is 8 to 1. If the length of a wing is 31.8 meters, how wide must it be?The airplane wing must be ____ meters wide.(Round to the nearest hundredth.)

Answer 1

Given

The ratio of the length of an airplane wing to its width is 8 : 1

length of the wing = 31.8 m

Find

how wide must it be?

Step-by-step explanation

as we have given the ration of length to width = 8 : 1

let width be x m

so ,

`\begin{gathered} (8)/(1)=(31.8)/(x) \\ 8x=31.8 \\ x=3.975 \end{gathered}`

Final Answer

Hence , the airplane wing must be 3.98 meters wide.
