Let's assume something else. If the spider moves faster than the ant, then it just needs to be on the surface, and then it will eventually catch up. Apparently, the task isn't about that.
Let's assume that due to freedom of movement, a speed of V is sufficient. The route is to move in a straight line towards the ant, no matter where it is.
So, what is the minimum speed the spider needs to move at to catch the ant? If the answer is that the minimum speed at which it needs to move to catch the ant is v, then that is incorrect. (I'm not claiming that it's insufficient.)
