| An athlete leaves one end of a pool of length L att = 0 and arrives at the other end at time t1. She swims back and arrives at the starting position at time tz. If she is swimming initially in the positive z direction, determine her average velocities symbolically in (a) the first half of the swim, (b) the second half of the swim, and (c) the round trip. (d) What is her average speed for the round trip?
