The traveling ant

Imagine an infinitely stretchy elastic band is tied to a tree on one end and to the bumper of a pickup truck on the other end. The truck, with an infinite tank of gas, drives away from the tree on an infinitely long straight road at a constant speed of 10 mph. Andy Ant walks with a constant speed of 0.1 mph relative to whatever surface he is standing on. When the truck has reached a point 0.1 miles from the tree, you place Andy on the elastic band at the tree and start him walking toward the truck.
Does Andy ever reach the truck?
