From 20 miles to 11 miles find each percent decrease. Round to the nearest percent

-45%

Step-by-step explanation:

To find the percent decrease, subtract the new value by the original value. Divide the result by the original value. Multiply the decimal by 100 to find its percent conversion.

11 - 20 = - 9

-9/20 = - 0.45

-0.45 * 100 = - 45%
