Question 176536
you must pay attention to your units and make sure you interpret what the rate is as opposed to the distance and time.
:
the rate is not 25 minutes..... the rate is  1mi/25min
:

so 7mi=(1/25)(mi/min)(t)
:
t=7mi(25/1 (min/mi))...see how the units cancel each other so that we end up with 175 min.
:
the way you were doing it you ended up with {{{(mi)^2/min}}}
