    In a 200 meter swimming race a swimmer swims down (in the +x direction) and back (in the -x direction) twice in a 50.00 m long pool. The swimmer's split times (for each 50.00 m segment) are 26.3 s, 30.1 s, 30.8 s, and 24.4 s. Assume the swimmer's speed is constant within each segment of the race. (a) What is the swimmer's average speed for the entire race? (b) What is the swimmer's average velocity for the entire race?...
