Last week, Christopher drove 480 miles
This week, Christopher drove 360 miles

The difference in miles this week compared to last week = 480 - 360 = 120 miles.

The percentage of decrease in miles compared to last week's  = (Difference in miles ÷ Total miles last week) multiplied by 100 = (120 ÷ 480) x 100 = 0.25 x 100 = 25%
