Inertia is the property of a body which allows it to resist any changes in its state of motion. Thus, because of inertia, a body will resist motion when the body is at rest. Likewise, a body will resist a change in motion when it is moving. Inertia of a body is related to its mass. The heavier the body, the more force is needed to overcome the resistance to change in state of motion (that is, inertia). For example, a more massive object needs more force to change its state of motion (say, moving it from a state of rest), as compared to a lighter object.
Thus, whoever is more massive between James and Brent will have higher inertia. If James is more massive than Brent, he would need more force to change his state of motion (running at a constant speed).
Hope this helps.
