Chapter 1, Problem 10CQ
Two friends watch a jogger complete a 400 m lap around the track in 100 s. One of the friends states, “The jogger's velocity was 4 m/s during this lap.” The second friend objects, saying, “No, the jogger's speed was 4 m/s.” Who is correct? Justify your answer.

I keep getting this question wrong, my first answer was 0 m/s and my second was 3 m/s. Please help, thank you so much!! :)
The men's world record for swimming 1500.0 m in a long course pool (as of 2007) is 14 min 34.56 s. At this rate, how many seconds would it take to swim 0.2500.250 miles (1 mi = 1609 m)?
June walks for 15 minutes at 0.165 km/ min but then she remembers she is suppose to meet her friend at the end of the path in 20 minutes. If the path is 5.2 km long what speed does she need to run within the last 20 minutes in order to be on time?
