He rows back to the original starting point to pick up his bait. How many meters has Horace rowed?

That is my problem. I drew the ellipse as they said i should. The major axis as 240 and the minor axis as 144 meters long. That means that a=120, and b=72. I solved for c and got c=96. When this is multiplied by two, this should give the distance between the foci (96*2=192). Where should i go now? Any help is appreciated.
