Jorge is running a race. In 2/3 of an hour, he ran 2 2/5 miles. At this rate, what distance will Jorge run in one hour?

The answer is 10. and if you go by pemdas you would 1. multiplication 2. division 3. addition 4. subtraction

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.
