Emma jogs 2 miles along the beach in 1/3   of an hour. if she travels at a constant rate, how far will she jog in an hour?

6 miles 
2 times 3 = 6

The answer is 6 miles.

2 x 3/3 = 6

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.
