Total trip distance = 250 miles
(1) The trip took Bill 5 hours.
Average speed = Total distance / Time
= 250/5
= 50 miles per hour
Sufficient
(2) At the midpoint of his trip, Bill was going exactly 50 miles per hour
Not sufficient

Hi
I was a bit confused here. Nowhere it is mentioned that if Bill stopped on the way in his trip. How can we calculate the average speed without knowing if he stopped or not.
Please help explain?
As per me answer should be E

Does it matter whether he stopped? We are told that the entire trip took Bill 5 hours. 5 hours include the stops if there were any.

(1) Sufficient. 250 / 5 = 50

(2) Can't determine average speed. Insufficient.

Avg speed = Total distance travelled/total time taken.

St. 1 Says total time is 5 hours.
250/5= 50 mph.
sufficient.

St. 2 says at mid point speed is 50mph. But we don't know what was the speed afterwards. It may be 50mph or even higher.
Insufficient.

A is correct.

The average speed is defined to be the total distance of the trip, divided by the total
time of the trip. The question stem tells us the distance from New York to Boston is
250 miles, so we can rephrase the question as "How long did it take Bill to drive from
New York to Boston?"
SUFFICIENT: Statement (1) tells us it took Bill 5 hours to drive from New
York to Boston, answering the rephrased question. In fact, his average rate of
speed equals 250/5 = 50 miles per hour.
INSUFFICIENT: Statement (2) tells us that at the midpoint of the trip Bill
was going exactly 50 miles per hour, but we can't figure out how long the trip
took from this information. Bill may have traveled at a constant rate of 50
mph throughout the whole trip, but he might also have been going faster or
slower at different times.
The correct answer is A
