Distance to your brothers house is 552 miles, and the distance to disneyland is 736 miles. if it took 12 hours to drive to your brothers house, how long would you estimate the drive to disneyland to take?

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.
