Answer
$33.9$ centimeters
Work Step by Step
There are 30.48 centimeters in a foot. This is a scale model, so the ratios of the length of the actual to the scale model and the ratio of the wingspan from the actual to the scale model are equal.
$\frac{230 * 30.48}{40} = \frac{195*30.48}{x}$
Simplify, Cross multiply and solve.
$7010.4/40 = 5943.6/x$
$7010.4x = 237744$
$x \approx 33.9130435$
Rounded to the nearest tenth, the answer is $33.9$ centimeters.
