The statement makes sense.

Work Step by Step

We know that $1 ~yard \approx 0.9~m$. We can convert the distance of 2000 yards to units of meters. $2000~yd = \frac{2000~yd}{1}\times \frac{0.9~m}{1~yd} = 1800~m$ One person ran a distance of 2000 meters in a given period of time. The other person ran a distance of 2000 yards in the same given period of time. Since 2000 yards = 1800 meters and the given time was the same, the person who ran 2000 meters ran at a faster rate. The statement makes sense.
