Kimberly and Varag are in a bicycle race.

1. If Kimberly's velocity in miles per hour during the race is $v(t) = 2.3^t \operatorname{sin}( \frac { t } { 2 } )$, find the bicyclist's average velocity during $0 ≤ t ≤ 6$. Describe your method.

   Hint(a):

   Average Velocity $= 16.102$ mph

2. If Varag's distance from the starting line during the race is $s(t) = 20t + 2\operatorname{ sin}(t)$, find his average velocity during $0 ≤ t ≤ 6$. Describe your method.

   Hint(b):

   Average Velocity $= 19.907$ mph

3. When is each bicyclist traveling at his/her average velocity?

   Hint (c):

   This is an application of Mean Value Theorem, which states that a function (such as a velocity function) must equal its average value at least once on a closed interval (that is, if the function is continuous and differentiable).
