B) 300 miles in 5 hours // 50*5 ≠ 300 (WRONG)
C) 200 miles in 4 hours // 50*4 = 200 (CORRECT)
D) 240 miles in 4 hours // 50*4 ≠ 240 (WRONG)

Answers: Choice A, Choice C, Choice E</h3>
=========================================================
Explanation:
We use this formula
speed = distance/time
to divide each pair of values given.
- For choice A, we have speed = distance/time = 250/5 = 50 mph which shows choice A is one of the answers.
- Choice B doesn't work though because 300/5 = 60 mph.
- Choice C works since 200/4 = 50 mph.
- Choice D doesn't work: 240/4 = 60 mph
- But choice E does work: 700/14 = 50 mph
To summarize, we got the following speeds
- A) 50 mph
- B) 60 mph
- C) 50 mph
- D) 60 mph
- E) 50 mph
