I believe your answer would be the following:
A) 250 miles in 5 hours.
C) 200 miles in 4 hours
E) 700 miles in 14 hour
Step-by-step explanation:
Unit rate = 50
A) 250 miles in 5 hours // 50*5 = 250 (CORRECT)
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)
E) 700 miles in 14 hours // 50*14 = 700 (CORRECT)
Hope this helps! :)

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
