It takes 2 hours to drive between the towns of Potter and Germantown. It takes 8 hours to make the trip by bicycle. How long would it take for a car and a bicycle to meet, starting at opposite towns at the same time?

Ais the answer for your question

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.

It is equivalent because the a ratio has to to have a “of” in it instead of a “for” therefore it will be equivalent
