Answer:
<h2>89.5°</h2>
Step-by-step explanation:
Using the vector formula 
|u| = magnitude of vector u
|v| = magnitude of vector v
u.v is the dot product of vector u and v
Given |u| = 88, |v| = 99 and u.v = 77, to get
we will substitute the given values into the equation above;

Let t = time
Between Rocky and Ken:
3000 + 3000(.10)(t)
Between Ken and Mike:
3000 + 3000(.12)(t)
Kens gain = The difference
