Acar will be traveling a total distance of 520 miles. the first part of the trip takes 2 hours, and the car’s average rate is 65 miles per hour. if the entire trip takes 8 hours, what is the car’s average rate, in miles per hour, during the second part of the trip? 49 57 50 65

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
