An average velocity question dealing with a relay race - Please help ASAP
The cheetah can run as fast as 113 km/h, the falcon can fly as fast as 161 km/h, and the sailfish can swim as fast as 105 km/h. The three of them run a relay with each covering a distance L at maximum speed.
a)What is the average speed of this relay team for the entire relay?
b) Compare this average speed with the numerical average of the three individual speeds. (Give you answer as a multiple of vav.)
c)Explain carefully why the average speed of the relay team is not equal to the numerical average of the three individual speeds.
