On a three-day trip, Wendy drove 125 miles on the first day, and 223 miles on the second day. How many miles did she drive on the third day, if the total miles that Wendy drove for the trip is 493 miles?
Wendy drove 125 miles + 223 miles = <<125+223=348>>348 miles on the first two days.
So on the third day, she drove 493 miles - 348 miles = <<493-348=145>>145 miles.
