Answer:
the answer would be a because 42÷6=7 and 42÷3=14.
Since you didn't list choices, I can only give you some guidance on the problem.
A kilometer is the length of 1000 meters. And a meter is about as tall as a normal desk height. So a kilometer is a relatively long distance compared to a desk.
It is also about half the length of a mile, or about 2 times around a normal athletic track.
Look for items that are long distance like that.
It would be around 9.304. so you'd round to the nearest tenth 9.3
