We are given dimensions of model and actual figure.
model: 9.5cm actual : 30.5m.
We need to find the length of actual shape for the scale factor 5cm.
Let us assume actual length be x m.
Let us set a proportion now.
<h3>5 : x = 9.5 : 30.5</h3>
Let us convert proportion into fractions.

On cross multiplying, we get 
9.5x = 5× 30.5 
9.5x = 152.5.
On dividing both sides by 9.5, we get 

x=16.05.
<h3>Therefore, the scale factor for a model is 5cm= 16.05 m.</h3>

Answer:
So the superhero covers 2450 miles in 30 minutes or 1/2 hour
Thus, he/she will cover (2450 x 2) miles in 1 hour
Therefore the answer is his/her velocity is (2450 x 2) miles/hour = 4900 miles/hour.
Hope this helps!
