To find the percent decrease from 20 miles to 11 miles, subtract the new value (11 miles) from the original value (20 miles): 20 - 11 = 9 miles. Next, divide the decrease (9 miles) by the original value (20 miles): 9 ÷ 20 = 0.45. Finally, multiply by 100 to convert to a percentage: 0.45 × 100 = 45%. Thus, the percent decrease is 45%.
