A won a race at the local fair by running miles in exactly hours. At this constant rate, how long does it take the same to run the -mile state fair race? Use ratio reasoning to solve.

Are you trying to figure out the volume?

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
