Here,
in y secs the rocket travel = \(\frac{x}{5}\)
So in 1 sec the rocket travel = \(\frac{x}{{5 * y}}\)
Therefore in 60z secs the rocket travel = \(\frac{x}{{5 * y}} * 60z = \frac{{12xz}}{y}\)
** z minute = 60z secs

In y sec rocket travel x/5 miles
in 1 sec rocket travel (x/5) /y miles
In 60z sec rocket travel (x/5) * 60z /y
= 12xz /y.
The best answer is E.
