Answer this science question please (physics)?

A 60.0-kg astronaut is on a space walk away from the shuttle when her tether line breaks. She is able to throw her 10.0-kg oxygen tank away from the shuttle with a speed of 12.0 m/s to propel herself back to the shuttle (Fig. P9.19). uming that she starts from rest (relative to the shuttle), determine the maximum distance she can be from the craft when the line breaks and still return within 57.0 s (the amount of time she can hold her breath).
