Big Boris (90kg) skates backward, 1.0 meter ahead of small skater Sofia (45 kg) , holding her hand as they travel 3.0 /s . At the 30-second mark, Boris starts pulling Sofia past him, so that by 32.0 s she is 1.0 m ahead of him. During that move, what was Sofia's average velocity, relative to Boris? -0.5 m/s -2.0 m/s +2.0 m/s -1.0 m/s +0.5 m/s +1.0 m/s
