When the chart above is filled out, the entries will show the distance by air between various airports. If a pilot plans to fly from airport P to airport R, then from airport R to airport S, and finally from airport S to airport Q, how many of the entries will he need to consult in order to calculate the total distance he will travel?

I do not understand the question so I just guessed.

The question asks for how many entries the pilot will have to look at. The chart shows the distances between airports. The columm and the row each show all the airports. If you drew a grid you would see boxes where you would put the distances. The distance from somewhere to itself is 0 so you would put a 0 for PP, QQ, etc.

In this case you need to look at the 3 entries to see the 3 distances so the answer is 3.
