Well, I don't know.
Let's figure it out together.
The best way to do that is to compare their unit rates:
The first woman's unit rate is (60 ft / 10 sec)
= (60 / 10) (ft/sec) = 6 ft/sec .
The second woman's unit rate is (25 ft / 5 sec)
= (25 / 5) (ft/sec) = 5 ft/sec .
Now we can see that the first woman walks 1 ft/sec faster
than the second one does.
