Your job is to figure out how to make a "silver mile". Here in the United States we could do this with nickels, dimes, quarters,

Ludmilka [50]

The total value of coins to create a silver mile following the specific rules stated is $38,114.18

<h3>Distance left:</h3>

63360 - 31650.48 = 31679.52 inches

A third of the distance is missing: 10559.84 inches

Diameter of the half-dollar: 1.205 in

This means 10,559.84 inches/ 1.205 in = 8763.35 rounded to 8764

Total distance coverd 8,764 x 1.205 in = 10560.61

Total distance left: 31679.52 - 10560.61 = 21118,91 / 4 = 5279.72

Diameter of quarters: 0.750 inches

This means 5279.72 / 0.750 =7039.62 rounded to 7040

7040 x 0.750 = 5280

Total distance left = 21118,91 - 5280 = 15,838.91 / 5 = 3167.782

Diameter of dimes: 0.705

This means 3167.82 / 0.705 = 4493.36 rounded to 4494

0.705 x 4494 = 3168.27

Total distance left = 15,838.91 - 3168.27 = 12670.64

Diameter of the nickel: 0.835

This means 12670.64/ 0.835 = 15174.41 rounded to 15175

<h3>How much money was used?</h3>

For this change the coins to dollars:

Susan B. Antony Silver dollars: 30462 = $30462

Half-dollars: 8764 = $4382

Quarters: 7040 = $1760

Dimes: 4494 = $561.75

Nickels: 15175 = $948.43

Total: $38114,18
