"Does anyone know the answer?"

Just pick a distance and do the math in your head.
30 miles works well.

First person takes one hour getting there and three hours back. Four hours total.

Second person takes 1.5 hours each way and with a elapsed time of 3 hours gets back first.

Thanks. I actually knew the answer last night, after I asked my question. I was in bed trying all different distances and I always came up with the 20/20 person winning. When I was taking the test, I kept thinking in a short distance the 30/10 person would win. I must have spent another half hour just playing with numbers in my head.
