In a race run by A and B, runner A beats B by 10 meters. When runners B and C run the same lap, B beats C by 20 meters.
What happens when runners A and C run the lap?
Note: Assume each runner's speed is constant.

cosθ∘+cos(θ∘+1∘)+cos(θ∘+2∘)+⋯+cos(θ∘+359∘)
What is the value of this expression when θ is an integer?
A certain theta value is shown here, but theta can be any integer. Consider how the cosine changes as the angle increases.
