An athlete swims the length of a pool in a time t, and makes the return trip to the starting position in a time tz. If she is swimming initially in the positive X-direction, determine her average velocities symbolically for the following. (Assume that time tz is from the other end of the pool to the starting point Use any variable or symbol stated above as necessary. Do not substitute numerical values; use variables only. Indicate the direction with the sign of your answer.) (a) the first half of the swim V avg X (b) the second half of the swim avg X (c) the round trip Vave 0 (d) What is her average speed for the round trip? average speed - X
