time = distance/rate
So, time = y/x

Answer: B

We know that

\(Speed=\frac{Dist}{time}\)

\(x=\frac{y}{time}\)

\(time=\frac{y}{x}\) (Units get canceled and we'll remain with hours)

We are given that Jennifer's rate is x, and we need to determine how long it will take her to run y miles. Since time = distance/rate, the time it takes her to run y miles is y/x.
