Sorry for rewording it wrong.

After 35 minutes of jogging, at the 9-km point in a total 10-km race, jogger A is behind the leader and moving at the same speed. What would have to be Jogger A's accelearation in order to catch up to the finish line? Assuming the leader maintains a constant speed the rest of the race.

Is the answer 3.7

I answered down below. You need to know how far behind but I showed you how to do it.

Hmmm, I see that this is the third time you have posted this without the whole problem and drwls told you you needed the distance behind the first time you posted it. You can not figure out how fast you have to go to catch up if you do not know how far behind you are.

George, there is not enough information here. We keep telling you that, and twice have shown you how to work it given that missing information. It seems to me that you are looking for us to post some answer you can put into an answer block. In that, you are wasting your time.

3.7 what? In physics, values without dimensions are useless, unless you are counting things like sheep.
