Hello!
There is technically not enough information in the problem, but the average human walking pace is about 1.5 yards a second. This means that you walk 90 yards in a minute. This means you walk 900 yards every ten minutes. This gives us the ratio 900:10, distance to minutes, so therefore you walk 90 yards in a minute, so in ten minutes you would walk 900 yards.
I hope this helps!
