If the city of Franklin lies along a certain route between the cities of Maple Valley and Viewcrest, what is the distance along the route from Franklin to Maple Valley?
(1) Traveling from Viewcrest to Maple Valley at an average rate of 45 m.p.h. takes 20 minutes longer than at an average rate of 50 m.p.h.
(2) Traveling along the route at a constant 25 miles per gallon of gas, a car will use twice as much gas between Maple Valley and Franklin as it will use between Franklin and Viewcrest.

I agree with OA.. C.

(1) Tells us about Viewcrest and Maple Valley but nothing about Franklin.
(2) We know of some relation among all three cities but we not enough (no rate, time, distance, etc.) to conclude the answer.
(combined) Suff.

oh.. it is a sloppy curved route...
still, how can we make sure that C is suff????

45(T+1/3)=50T ..is it to be multiplied with "per gallons" ??

A alone is not sufficient
t1 = d/45 = t2+20 = d/55
You can only find the distance d here.

B gives the ratio between the distances.

so A and B both are needed.
