A satellite moves at a speed of 2.4 x 10^4 km/h. Work out how long it will take for the satellite to move a distance of 3.2 x 10^6 km. Give your answer in standard form to 3 significant figures

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.
