If instead, the swimmer makes 77.5 laps in the same pool in 1.5 h, determine the total distance the swimmer traveled, the swimmer's total displacement, the swimmer's average velocity, and the swimmer's average speed.

and your thinking is...? I will be happy to check your work.
Answered by Dave
I just have the the total distance traveled. 7750
Answered by bobpursley
avg speed=distancetraveled/timetotal

avg velocity=displacement/time=0/time
Answered by Dave
I put 5.17km/h because it asks for it in km also i put 0 for avg velocity and that's wrong

If you have swam one lap in a swimming pool, that means you have swam from one end to the other and back. In 1.5 h, a swimmer makes exactly 77 laps in a swimming pool that is 27 m long. Determine the distance the swimmer traveled, the total displacement of the swimmer, the swimmer's average velocity, and the swimmer's average speed.

oops, displacment is 77.5 laps, so he net displacment is the pool length. Avg velocity = displacement/time
