The paper considers a two-player differential game of the pursuit-evasion type. The main result is that the capture time is the unique solution, in the viscosity sense [see e.g., M. G. Crandall and P.-L. Lions, Trans. Am. Math. Soc. 277, 1-42 (1983; Zbl 0599.35024)] of the induced boundary value problem. An analogous result for the minimum time problem of optimal control theory was proved by M. Bardi [SIAM J. Control Optimization 27, No.4, 776-785 (1989)].
