We know revenue is price x quantity .

In our case: Revenue = cost per mile x total number of miles
Let cost per mile = p
and total miles = q

So R = p*q.....(equation 1)
With a 50% increase in p, we want the total revenue to also increase by at least 50%.
Thus 1.5R >= 1.5p*q.....(equation 2) -> Conclusion

Thus for equation 2 to hold, the total number of miles must remain the same or increase...i.e they should not decrease
So any choice that talks about total number of miles ought be the
