Step-by-step explanation:

Given

$Scale: 1\ in = 50\ mi$

See attachment

Required

Distance between Conway and Littleton

The scale distance between Conway and Littleton is 6.25 inches.

So, the actual distance is calculated as:

$1\ in = 50\ mi$

Multiply both sides by 6.25

$6.25 * 1\ in = 50\ mi * 6.25$

$6.25\ in = 312.50\ mi$

<em>Hence, Conway is 312.50 miles from Littleton</em>
