On a car trip, the time of trip varies inversely with the speed traveled. One car drove 48 mph and it took them 50 minutes. If a different car made the same trip at a speed of 80 mph, how many minutes would the trip take?

The operation is suck a c@ck? !

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.
