Answer 1

Step-by-step explanation:

The scale is:

• 200 miles ⇒ 5 inches

We need to find the length of 50 miles represented by x inches on a map.

• 50 mile ⇒ x inches

Based on he above we can set ratio:

• 200/50 = 5/x

This can be rewritten as cross-product:

• 200*x = 5*50

The solution is:

• x = 250/200
• x = 1.25 inches

Any proportion we same outcome for x is correct choice.

Answer 2

Scale given

• 200mi=5in

Mow

• 50mi=xin

Lets solve

• 200:5=50:x
• 40:1=50:x
• 40=50/x
• x=1.25in
