given: T=4 (hours), D is a total distance, find average S (speed)-?
st(1) t(1)=2, D(
part of the distance)=100, S(1)=100/2=50 since we don't have information about the total distance and the time or speed of bus for the second half of the distance - Not Sufficient;
st(2) S(2) speed for half of the distance=2*S(3) speed for the second half, BUT we don't what's the
half of distance - Not Sufficient;
Combined: we have no reference points in st(1&2) Not Sufficient, hence E.

1. In the first 2 hours the bus covered 100 miles
2. The average speed of the bus for the first half of the distance was twice its speed for the second half
